aicher

Aicher is a rare, dialectal verb meaning to bait a hook with live or artificial bait before fishing — a variant of the more standard escher. It survives mainly among older or regional French anglers rather than in general vocabulary.

• Le pêcheur aiche son hameçon avec un ver de terre. — The fisherman baits his hook with an earthworm.
• Il faut bien aicher avant de lancer la ligne. — You need to bait properly before casting the line.
• Les jeunes pêcheurs préfèrent dire escher plutôt qu'aicher. — Young anglers tend to say escher rather than aicher.

Learners searching for "to bait a hook" are more likely to encounter the standard form escher — aicher is a regional variant that means exactly the same thing but is far less common in dictionaries and modern usage.
