'Teilweise' (partly) is made up of 'der Teil' (the part) and the ending '-weise'. It literally means 'in the manner of a part'. The ending '-weise' often forms adverbs from nouns.
Normalerweise beginnt der Unterricht um 8 Uhr.
Normally, class begins at 8 o'clock.
As an adverb, 'teilweise' (partly) can stand flexibly in the sentence. At the beginning of the sentence (position 1), the verb moves to position 2. In the middle of the sentence, it usually stands before the word it describes more closely.
Teilweise waren die Geschäfte schon geschlossen.
Some of the stores were already closed.
Common combinations are 'teilweise richtig' (partly correct), 'teilweise fertig' (partly finished), 'teilweise bewölkt' (partly cloudy), or also verbs such as 'teilweise zustimmen' (to partly agree).
Deine Antwort ist leider nur teilweise richtig.
