Nouns and articles
A word that refers to a person, place, thing, or idea.
How to spot it. In Spanish, nouns often appear with an article such as el, la, los, las, un, una. Many have common endings like -o, -a, -ción, -dad, and they usually control agreement in articles and adjectives: la casa blanca, los libros nuevos.
Watch out. Do not guess gender from meaning alone: la mano is feminine, but el problema is masculine. Also watch words that can be different parts of speech depending on context, and check the dictionary label and article.
The masculine singular definite article.
How to spot it. You see el before a singular noun treated as definite: el libro, el coche, el hombre. It also appears before many masculine singular adjectives used as nouns, as in el rojo.
Watch out. El is also used before feminine singular nouns beginning with stressed a- or ha-: el agua, el águila. That does not make the noun masculine, so adjectives stay feminine: el agua fría.
The feminine singular definite article.
How to spot it. You see la before a definite feminine singular noun: la casa, la mesa, la mujer. It is common with nouns ending in -a, -ción, -sión, -dad, -tad, -umbre.
Watch out. Do not assume every noun in -a is feminine: el día, el mapa, el problema are masculine. Also remember that some feminine nouns take el instead of la in the singular for sound reasons, like el agua.
The plural definite article for masculine nouns and for mixed-gender groups.
How to spot it. You see los with definite plural nouns treated as masculine: los libros, los coches. It is also the standard plural article for mixed groups, as in los niños for boys or for boys and girls together.
Watch out. Learners often read los as meaning only male referents, but it can also mean a mixed group. Check the context before deciding whether it means masculine-only or inclusive masculine plural.
The plural definite article for feminine nouns.
How to spot it. You see las before definite plural nouns that are feminine: las casas, las mujeres, las ciudades. Adjectives usually confirm it by agreeing in feminine plural too: las casas blancas.
Watch out. Las is used only when the whole group is feminine. If even one member is grammatically masculine, standard Spanish normally switches to los.
Verbs
A word that describes an action, state, or experience.
How to spot it. Spanish verbs change form a lot, so look for endings such as -o, -as, -a, -amos, -an, -é, -ó, -ía. A full clause usually has a conjugated verb, though the subject pronoun is often omitted: Hablo español.
Watch out. Do not expect Spanish to always show the subject word, because the verb ending often already tells you who does the action. Also learn common irregular verbs early, especially ser, estar, tener, ir, and hacer.
A small set of verbs that add meaning like ability, obligation, certainty, or permission to another verb.
How to spot it. Spanish has no single closed class exactly like English modal verbs, but dictionaries may use this label for verbs such as poder, deber, and sometimes soler. They usually appear before an infinitive: puedo ir, debes estudiar, suele llover.
Watch out. Do not force English modal rules onto Spanish: these verbs do conjugate normally and can appear in many tenses. Learn the Spanish pattern as a full structure, especially poder + infinitive and deber + infinitive.
A verb followed by a small word that together carry a different meaning from the verb alone.
How to spot it. Spanish does not really build verbs the way English phrasal verbs do, so this label is uncommon in Spanish dictionaries. If you meet it in learner materials, it usually points you to a fixed multi-word meaning such as volver a, dejar de, or an idiomatic verb-plus-preposition pattern.
Watch out. Do not try to translate English phrasal verbs word for word into Spanish, because Spanish usually uses a different single verb or a fixed expression. Learn the whole Spanish expression as one unit instead of matching each small word.
A verb that conjugates with a reflexive pronoun.
How to spot it. In dictionaries, these verbs are listed with -se: lavarse, quejarse, arrepentirse, irse. In real sentences, the pronoun changes with the subject: me lavo, te quejas, se arrepienten.
Watch out. The -se form is not always literally reflexive, and the meaning may differ from the plain verb: ir is "to go" but irse is often "to leave". Also learn any preposition that belongs with it, as in acordarse de.
Other parts of speech
A word that stands in for a noun so you do not have to repeat it.
How to spot it. Spanish pronouns include subject forms like yo, tú, él, object forms like me, lo, la, and stressed forms after prepositions like mí, ti. Clitic object pronouns often come before a conjugated verb: lo veo, me llama.
Watch out. Spanish object pronouns are a major trouble spot: lo, la, le do not work like English "him/her/it" one-to-one. Check whether the verb takes a direct or indirect object, and learn common combinations such as se lo.
A word placed before a noun to specify which one or how many.
How to spot it. In Spanish, determiners come before the noun, sometimes before an adjective plus noun: este libro, muchas casas, mi nuevo coche. Articles, demonstratives, possessives, and quantifiers all commonly behave this way.
Watch out. Do not stack determiners the way English sometimes seems to allow; Spanish usually chooses one main determiner slot: mi libro, not el mi libro. Also watch agreement in gender and number: esta mesa, estos libros.
A word used before a noun, pronoun, or noun phrase to show its relationship to another word.
How to spot it. Common Spanish prepositions are short words such as a, de, en, con, por, para, sin, and sobre. They usually stand right before a noun phrase or infinitive: en casa, para estudiar, de María.
Watch out. Prepositions rarely match English exactly, so do not translate them mechanically. Learn fixed patterns like pensar en, depender de, soñar con, and remember the personal a before many human direct objects.
A word that links two parts of a sentence.
How to spot it. Spanish conjunctions include coordinating words like y, o, pero and subordinating ones like que, porque, aunque, si, cuando. They usually sit at the start of the second linked part: vino, pero no habló.
Watch out. Watch for mood changes after some conjunctions, especially with the subjunctive after patterns like aunque, para que, or antes de que in the right context. Also remember spelling changes such as e before words beginning with i- sound and u before o- sound.
A short word or phrase that expresses a sudden feeling or reaction.
How to spot it. Spanish interjections often appear with exclamation marks and can stand alone: ¡ay!, ¡oh!, ¡eh!, ¡anda!, ¡ojalá!. If you remove them, the rest of the sentence usually still works grammatically.
Watch out. Some interjections are very colloquial or region-specific, so do not assume they work everywhere. Also remember Spanish punctuation uses opening marks: ¡Ay! not just Ay!.
A short word that signals whether a noun is specific or general.
How to spot it. Spanish articles include definite forms el, la, los, las and indefinite forms un, una, unos, unas. They usually come directly before the noun, sometimes before an adjective plus noun: la casa blanca, un libro interesante.
Watch out. Spanish uses articles differently from English, so do not copy English article use blindly. Spanish often uses the definite article for general statements and with body parts or days: Me duele la cabeza, Los lunes trabajo.
A word that refers to a quantity or a position in order.
How to spot it. Cardinal numbers like uno, dos, veinte usually count things, and ordinal numbers like primero, segundo show order. Before masculine singular nouns, uno becomes un and primero/tercero shorten to primer/tercer: un libro, primer día.
Watch out. Learners often miss agreement and shortening forms: una casa but veintiuna casas; primer piso but primera vez. Also note that Spanish often uses cardinal numbers where English prefers ordinals, especially in names and dates.
