-ABLE means "capable of being done" or "worthy of." READABLE (can be read), COMFORTABLE (can provide comfort), RELIABLE (can be relied on). From TABLE and CABLE to COMFORTABLE and UNFORGETTABLE, -ABLE words span every length in word games.
The suffix -ABLE (and its variant -IBLE) comes from Latin -abilis and means "capable of being done" or "worthy of being done." READABLE = capable of being read, ADORABLE = worthy of being adored, VALUABLE = worthy of being valued. When you see -IBLE instead of -ABLE (FLEXIBLE, VISIBLE, HORRIBLE), the meaning is identical — the spelling varies based on the Latin root of the base word. -ABLE attaches to native English verbs; -IBLE attaches to Latinate roots.
