Formation
Noun + しか + Verb（negative form）
Verb（dictionary form）+ しかない ※ Same meaning: “have no choice but to”
Explanation
「しか〜ない」 is used to emphasize that something is limited strictly to one option, and it must always be followed by a negative form.
Key nuance:
Strong limitation
Excludes all other possibilities
Often expresses lack or restriction
Can imply resignation (no choice)
It is stronger and more restrictive than だけ.
