I have just a quick question about the pronunciation of a simple phrase. I know that 高い is pronounced takai, and it means tall. So does that mean 高かったビル is it pronounced
takakattabiru? The reason I ask is that takakattabiru sounds a little awkward, or it could just be my ears are not accustomed yet.
Yes, it's takakatta biru. Generally a kanji's reading will be set, and what changes is the part written in hiragana after it. So 高 followed by hiragana is going to be read taka, and then the hiragana add the tense and whatnot.
I do add a little accent to the second "ka" because of the little tsu preceding "ta." More specifically, I pause briefly while holding the pronunciation.
高かったビル implies that the building is no longer high (like "the building which used to be high"), maybe new building which is higher than the building in question has been built, or more likely the building crumbled down or something and became lower than it used to be.
