Sign for -ICAL Suffix in ASL
Quick answer: The -ICAL suffix in ASL is fingerspelled I-C-A-L. It is useful for recognizing longer descriptive endings in fingerspelled English words.

How to Recognize -ICAL
The ending I-C-A-L is longer than -IC, but that can actually help. Once students recognize it as a chunk, they do not have to rebuild the word from scratch.

Why It Matters
-ICAL often appears in academic, technical, or descriptive vocabulary. Recognizing it helps students move from slow letter tracking into pattern-based reception.
