Pronouncing words with more than one つ
There are several words with double つ's but I'm kind of unaware of how it's actually pronounced.
For example: 人は泣きつつ生まれ、泣き言を言いつつ暮らし、失望落胆して死ぬ
Would the timing be the similar as reciting かきくけこ for instance, or more like how ます/です changes a bit? Or even something like "まじっすか！？" Is there a term for that? 音変化 is for readings right? Would I be correct in assuming that 五つ is pronounced more like いつ・つ rather than い・つ・つ? More words that contain it are 包む、現つ、慎む and 突付く.
「つつ」in the sample sentence is used as conjunction, linking two events and explaining those events are happening at the same time. This つつ is always pronounced with the immediate previous word; 「泣きつつ」should be pronounced as if they are a one word. If you separate 泣き and つつ, it sounds a bit unnatural. 「つつ」itself is pronounced just as is, tsu tsu, 2 syrable.
There is another way to use 「つつ」, which describes changing its stage/situation and so on. i.e., 寒くなりつつある(it's getting cold) 良くなりつつある(it's getting better)
in casual conversation, you can also say つっつく
Hope it helps ;)
