the word 'tallish' is a modern english formation, combining the native english adjective 'tall' with the productive suffix '-ish'. the root 'tall' has an intriguing history, originating from an old english word meaning "prompt" or "ready," which evolved through meanings like "brave" before settling on its current primary sense of "high in stature" around the 1500s. the suffix '-ish' is of germanic origin, a common and versatile tool in english for creating adjectives that imply a moderate degree of the quality described by the root. therefore, 'tallish' logically constructs its meaning as "somewhat tall," following a transparent pattern where the ancient suffix softens the definitive quality of the core adjective, a process that remains highly intuitive for contemporary word formation.
