Questions & Answers about Я запомню это слово.

Why is запомню used instead of помню?

помню is the present‐tense, imperfective form meaning “I remember (right now).” запомню is the first‐person‐singular future of the perfective verb запомнить, so it means “I will remember” or “I will memorize” a specific word in the future.

What’s the difference between the imperfective verb запоминать and the perfective запомнить?

Imperfective запоминать focuses on the process or habitual action (“to be memorizing,” “to memorize repeatedly”) and cannot form a simple future (you’d say я буду запоминать). Perfective запомнить denotes a single, completed action (“to succeed in memorizing”), and you get a simple future like я запомню.

Why is это слово in the accusative case, and how does слово decline?

Это слово is the direct object of the verb запомню, so it takes the accusative case. Neuter singular nouns have the same form for nominative and accusative. Singular declension of слово:

• Nominative/Accusative: слово
• Genitive: слова
• Dative: слову
• Instrumental: словом
• Prepositional: слове

Why is the demonstrative это used here instead of этот, эта or эти?

Demonstratives agree in gender, number and case with the noun they modify. Слово is neuter singular, nominative/accusative, so the correct form is это. The full paradigm in nom/acc:

• Masculine: этот
• Feminine: эта
• Neuter: это
• Plural: эти

Where is the stress in запомню, and how do you pronounce it?

The stress falls on the second syllable: за-по́-мню. Phonetically you’ll hear [zə-póm-nʲu]. Make sure the о is stressed, not the я or ю.

What does the prefix за- add to the meaning of помнить?

The prefix за- turns помнить (imperfective “to remember/to have in mind”) into the perfective запомнить, emphasizing the action of “getting something into memory” or “learning by heart.” It signals that you complete the act of memorization.

How would I say “I have already memorized it” in Russian?

Switch to the past tense of the perfective:

• Male speaker: Я запомнил это слово.
• Female speaker: Я запомнила это слово.

How can I say “I will remember those words” (plural) instead of “this word”?

Use the plural noun and matching demonstrative:
Я запомню эти слова.
Or replace эти слова with a pronoun: Я их запомню (where их is the plural accusative of “they”).
