Questions & Answers about Она положила лак для ногтей в косметичку.
Why is the verb положила and not положить?
Положить is the dictionary form, meaning to put / to place.
Положила is the past tense form, and it agrees with a feminine singular subject:
- он положил = he put
- она положила = she put
- оно положило = it put
- они положили = they put
So because the subject is она (she), the verb becomes положила.
Why does положила end in -а?
In the Russian past tense, verbs usually show the gender of the subject in the singular.
For положить:
- masculine: положил
- feminine: положила
- neuter: положило
- plural: положили
Since она is feminine, the verb takes the feminine ending -а: положила.
