The difference between "ぶら下がる" and "つり下がる" in terms of usage


As mentioned in the title, I want to ask about the difference between "ぶら下がる"
and "つり下がる" in terms of usage. Both of them are translated as "hang".

For example

> 服が 鉄棒に つり下がる/ぶら下がる
>
> 手が つり革に つり下がる/ぶら下がる

Are the two words interchangeable?




The only difference worth mentioning, as far as I am concerned, is in the word
formation of the two words.

「ぶら下{さ}がる」 is formed by combining an **_onomatopoeia and a verb_** --
「ぶら/ぶらり（と）」 and 「下がる」.

「つり下がる」 is formed by combining **_two verbs_** -- 「吊{つ}る」 and 「下がる」.

For using an onomatopoeia, 「ぶら下がる」 sounds just a tiny bit more informal and
slightly more intuitive than 「つり下がる」 for the native speakers. The difference
is minimal in actual usage. For this reason, I would say that the majority of
native-speaking children would get to learn to say 「ぶら下がる」 before 「つり下がる」.

If you used the two interchangeably, I doubt if anyone would even notice
anything.
