What does ayer estudié mean?
Ayer estudié combines the time word ayer (yesterday) with the past tense verb estudié (I studied). It tells someone that you studied at some point the day before today. Use this phrase to describe completed actions that happened yesterday.
In English the literal idea is I studied yesterday. In Spanish you usually put ayer either before or after the verb. Both orders are correct and common: Ayer estudié or Estudié ayer.
Basic sentence structure
Use the simple past (pretérito perfecto simple) for actions finished yesterday. The pattern is:
Time word + verb: Ayer estudié
Or verb + time word: Estudié ayer
Both forms are natural. Placing ayer at the start often emphasizes the time. Placing it after the verb can emphasize the action instead.
Quick examples

Estudié ayer para el examen.
Ayer estudié con mi amiga.
