The word "涵盖" is formed by combining the character "涵", which uses the water radical (氵) to imply containment and the phonetic component "函" for sound and semantic reinforcement, with "盖", which uses the grass radical (艹) to suggest covering and the phonetic component "盍" for sound and related meaning; together, they create a compound meaning "to cover" or "to encompass", where "涵" contributes the sense of inclusion and "盖" contributes the sense of coverage.
