What Does -ABLE Mean?
The English suffix -able means “capable of being” or “able to be.” In ASL, this suffix is usually not a standalone sign. When the English form needs to be shown directly, especially in grammar instruction, vocabulary study, or fingerspelling practice, it is fingerspelled as A-B-L-E.
When to Use It
Use the fingerspelled -ABLE suffix when you are explaining English word structure, spelling a word ending, or teaching how suffixes change meaning. For example, words like readable, doable, and manageable all include the idea of something being possible or capable of being done.
When Not to Use It
Do not automatically fingerspell -ABLE in everyday ASL conversation if there is a natural ASL sign or phrase that expresses the meaning more clearly. ASL does not rely on English suffixes in the same way written English does.
Common Mistakes
- Rushing the fingerspelling so the letters are unclear.
- Using the suffix as if it were a standalone ASL sign.
- Forgetting that ASL may express the same idea with signs like CAN, POSSIBLE, or context.
Example
