This is the 14139th most frequent Turkish word.
muydu
"Was it?"
The word 'muydu' is used here as a part of a question, combining 'mu,' the interrogative particle, with 'idi,' the past tense auxiliary, to inquire about the state of the weather yesterday.
Dün hava güneşli miydi?
Was the weather sunny yesterday?
In this case, 'muydu' stems from 'mu' (interrogation) and 'idi' (past tense auxiliary), used to question if this is the same toy as before.
Bu aynı oyuncak mıydı?
Was this the same toy?
Here, 'muydu' is formed from 'mu' (the interrogative particle for yes-no questions) and 'idi' (past tense auxiliary), questioning the quality of the movie in the past.
