Questions & Answers about Учительница сказала, что мой почерк стал лучше, когда я начал писать медленнее.
Учительница is the feminine noun meaning female teacher. Russian often has gendered job titles:
- учитель = (male) teacher
- учительница = (female) teacher (also commonly used for a woman teaching children/school)
Both are grammatically correct; the choice tells you the teacher is a woman.
сказала is past tense, feminine singular of сказать (to say, perfective). It agrees with учительница (feminine subject).
Compare:
- он сказал (he said)
- она сказала (she said)
- они сказали (they said)
Perfective сказать focuses on the fact the statement happened (a completed act of speaking).
Because Russian uses a comma before a subordinate clause introduced by что (that):
- Учительница сказала, что… = The teacher said that…
This is standard reported speech structure.
