Learning objectives

By the end of this guide you will be able to:

  • Translate every Unit 7 word in both directions, English to Spanish and Spanish to English
  • Spot a sentence and instantly know whether it wants the imperfect or the preterite
  • Conjugate any regular verb in the imperfect, plus the three irregulars (ser, ir, ver)
  • Apply the right spelling change to preterite yo forms of buscar, tocar, sacar, llegar, gozar, leer, caer, oír, construir
  • Apply the e→i and o→u stem change to the third-person preterite of dormir, pedir, sentirse, reírse, mentir

TL;DR

Unit 7 is La Niñez (childhood). You need to memorize 36 vocabulary words split into four groups (time markers, nouns, adjectives, verbs), plus three grammar patterns (imperfect endings, preterite spelling changes, preterite stem changes). Every quiz question, flashcard, and self-test in this guide is English prompt → Spanish answer, so you practice the harder direction.

Time markers for the imperfect

The imperfect tense (full grammar in §8) describes habitual or repeated actions in the past. These 12 phrases are the giveaway that a sentence wants the imperfect.

Grammar 1: The imperfect tense

Use the imperfect when something happened repeatedly, was ongoing, or sets the scene in the past. Translation hints: “used to ___,” “would ___,” “was ___-ing.”

Cuando era niño, jugaba con mis muñecos todos los días. When I was a child, I used to play with my dolls every day.

Grammar 2: Spelling-change preterite verbs (yo form)

Nine verbs from the unit change only in the yo form of the preterite, to keep the original sound.

VerbChangeyo form
buscar (to look for)c → qu busqué
tocar (to play instrument)c → qutoqué
sacar (to take out / get a grade)c → qusaqué
llegar (to arrive)g → gu llegué
gozar (to enjoy)z → c gocé
leer (to read)i → y in 3rd personleí, leyó, leyeron
caer (to fall)i → y in 3rd personcaí, cayó, cayeron
oír (to hear)i → y in 3rd person, oyó, oyeron
construir (to build)i → y in 3rd personconstruí, construyó, construyeron
Walk through: preterite yo form of tocar 1 / 3

Grammar 3: Stem-changing preterite verbs (3rd person)

Five verbs from the unit change their stem vowel in the third-person singular and plural of the preterite.

VerbStem changeél / ella / ustedellos / ustedes
dormir (to sleep)o → u durmiódurmieron
pedir (to ask for)e → i pidiópidieron
sentirse (to feel)e → ise sintióse sintieron
reírse (to laugh)e → ise rióse rieron
mentir (to lie)e → imintiómintieron

Practice problems

Q Translate to Spanish: 'I used to play with my dolls every day.'

Yo jugaba con mis muñecas todos los días.

  • “used to play” → jugaba (imperfect, repeated childhood action)
  • “every day” → todos los días (a giveaway time marker for imperfect)
  • “dolls” → muñecas (feminine plural)
Q Conjugate ser in the imperfect (all six forms).

era, eras, era, éramos, erais, eran

Ser is one of only three irregular verbs in the imperfect (the others are ir and ver).

Q What spelling change does buscar undergo in the preterite yo form, and why?

c → qu, giving busqué.

Without the change, buscé would be pronounced “boos-SAY” (soft c before e). Changing to qu keeps the original “k” sound of buscar.

Q Translate to Spanish: 'He fell from the tree.'

Él se cayó del árbol.

Caer is reflexive when describing accidental falls (caerse), and the third-person preterite of caer is cayó (i→y change).

Q Why is molestar grammatically weird?

It conjugates like gustar. The thing that’s bothering is the subject; the person being bothered is the indirect object.

  • Me molesta el ruido. = The noise bothers me. (literally: “to me, it bothers, the noise”)
  • A mi hermano le molestan los lunes. = Mondays bother my brother.

The verb agrees with the THING, so it’s molesta for one thing or molestan for several.

Q Imperfect or preterite? 'Mientras yo leía, mi hermano dormía la siesta.'

Both verbs are imperfect (leía, dormía).

Mientras (while) is one of the unit’s imperfect time markers. Both actions are ongoing in the past, neither has a defined endpoint, so both stay imperfect.

Mnemonics

“SIV” for the three irregulars in the imperfect: Ser, Ir, Ver. Every other Spanish verb is regular in the imperfect.

“Hard sounds want hard friends” for spelling-change preterites:

  • C wants to stay hard “k”, so before -é it becomes qu (toqué, busqué, saqué)
  • G wants to stay hard “g”, so before -é it becomes gu (llegué)
  • Z can never sit before -e, so it becomes c (gocé)

“OUI” for stem-change preterites:

  • O becomes U (dormir → durmió)
  • E becomes I (pedir → pidió, sentirse → sintió, reírse → rió, mentir → mintió)

Only the third person changes. yo/tú/nosotros stay the same.

Common pitfalls

  • Forgetting the accent on -íamos / -íais. The imperfect of comer (we form) is comíamos, not “comiamos.” The accent flips the stress to the í.
  • Picking preterite when the time marker says imperfect. “Cada día” or “siempre” or “mientras” almost always means imperfect, even if the action seems “completed.”
  • Treating molestar like other -ar verbs. It’s gustar’s twin. “I bother him” = Le molesto a él is wrong. Correct: A él le molesto.
  • Saying muñeca for action figure. La muñeca is a girl’s doll. El muñeco is what you use for action figures or boy dolls.
  • Spelling dibujos animado (singular). Always plural: dibujos animados.
  • Adjective agreement for plural feminine. Las niñas son cariñosas (not cariñoso). The adjective takes -a AND -s.
  • Confusing leyó with leía. Leyó is preterite (he read, one time). Leía is imperfect (he used to read / was reading).
