Etymology
The surname Nair is usually treated as a Gaelic name, and the historical literature gives more than one explanation for it. One line of interpretation connects it with Gaelic elements meaning “son of the heir,” while another links it to a form meaning “son of the abbot.” Some writers also relate it to older Gaelic bynames and local clan forms, so the exact origin may differ by family branch.
History
The name is especially associated with Scottish Gaelic families, and historical forms such as MacNair, Macnayr, and M'An-uidhir appear in older records. Macbain notes different explanations for different branches, including a Perthshire form and a Gairloch branch. The surname is still most strongly associated today with Scotland and the wider Gaelic diaspora.
