The surprisingly eventful life of into
Into began as two words. In late Old English, in and to fused into intō as the language’s case endings faded. Those endings had once helped distinguish being inside a place from moving toward its interior, so the new preposition inherited the job of carrying something across a boundary.

English eventually pushed that crossing far beyond rooms and doorways. A person can run into a wall, turn water into ice, go into medicine, or be into jazz. That last sense—being intensely involved or interested—appears in records of American youth slang by 1967.

4 letters and 2 syllables.
Common pronunciations are /ˈɪntuː/ and the reduced /ˈɪntə/.
Although it names a spatial relation, into usually signals movement or change; in usually describes an already occupied location.
Into stays one word in “walked into the room.” In “walked in to speak,” in belongs to walked and to begins the next phrase.
Its meanings now cover entry, collision, transformation, occupation, investigation, and enthusiasm.
