What is the reading of 弓形?


The word 弓形 has three different readings which are きゅうけい, ゆみがた, and ゆみなり.
Unfortunately, there does not seem to be much distinction between these three
readings. Is this simply a case wherein all readings are acceptable or is one
reading more common than the others?




The kun-reading ゆみがた is the safest reading at least in ordinary speech and
writings.

弓形 may be read きゅうけい in some technical fields I'm not good at, but I can say
it's rare. In mathematical contexts, this word is normally called ゆみがた (see

this [Wikipedia article](https://ja.wikipedia.org/wiki/%E5%BC%93%E5%BD%A2) for
example), not きゅうけい. I guess this is because there is a more common word with
the same reading, 球形 ("spherical").

ゆみなり is a common word, but it's usually written as 弓なり in modern Japanese.
