Lacking firmness; unstable, weak, or lacking in determination or resolve.
Formed from 'firm' + the Old English suffix '-less' (meaning without or lacking). This construction allows any adjective to be negated, creating the opposite quality.
The beauty of English's '-less' suffix is that it's productive—you can add it to almost any adjective to flip its meaning, but 'firmless' is rare because 'soft' or 'weak' work better.
