Lacking experience; having no or very little experience with something.
From 'experience' plus the '-less' suffix. While 'inexperienced' is the standard form, 'experienceless' follows regular English word-formation patterns.
We say 'inexperienced' instead of 'experienceless,' but both are grammatically valid. 'Inexperienced' sounds better because the prefix 'in-' feels more natural with 'experienced' than just tacking '-less' onto 'experience.'
