The short answer
Ian is a masculine Scottish and English name, pronounced EE-ən. Behind the Name describes it as the anglicised form of Scottish Gaelic Iain, which itself comes from Latin Iohannes, the source of John; so Ian is a Scottish form of John. Behind the Name lists the roots as Yahweh and ḥanan, but the John entry was not available in this pass, so the usual gloss of John is left unverified here. The name became popular in the United Kingdom outside Scotland in the first half of the 20th century and did not catch on in America until the 1960s. In the United States it ranked #83 for boys in 2025.
Meaning and etymology
Behind the Name gives Ian as the "anglicized form of Scottish Gaelic Iain, itself from Latin Iohannes (see John)". The chain is therefore Ian, from Iain, from Latin Iohannes, and the entry's root line reads "Yahweh + ḥanan", the same roots it assigns to John. The Behind the Name entry for John was not in the material available for this profile, so the meaning of those roots is not glossed here; a reviewer should add it from the John entry. On usage, Behind the Name says Ian "became popular in the United Kingdom outside of Scotland in the first half of the 20th century, but did not begin catching on in America until the 1960s". The Gaelic spellings Iain and Eòin are listed as variants.
