[v1 stem] + づらい [v5 stem] + づらい [する → し] + づらい [来る → き] + づらい
Conjugates as い-adjective:
The suffix づらい attaches to the verb stem (masu-stem) to express that an action is difficult, hard, or painful to do. It carries a nuance of personal difficulty – often implying physical discomfort, psychological burden, or emotional pain associated with performing the action.
V[stem] + づらい
Since づらい is an い-adjective ending, it conjugates like any い-adjective:
づらい emphasizes that the person doing the action feels difficulty or discomfort. It is most naturally used when the subject is a person (or living thing) who experiences the hardship.
Both づらい and にくい can mean "hard to do," but they differ in nuance:
For example, わかりにくい分かりにくい (hard to understand) is natural, but 分かりづらい sounds less natural because わかる分かる is not a volitional action.
