What's on your mug?

A term of endearment, chiefly for a beloved [wife]; darling, dear one. Also (extended sense): a woman, typically a [wife] and mother, in whom the following qualities are present together — devotion as a partner and parent; intelligence carried with humility; simultaneous [cuteness] and irresistibility; responsibility and quiet discipline. Used as a common noun, as a proper noun for a specific individual, and attributively (esp. in chellslike behaviour).

Etymology. Anglicized hypocoristic of Tamil செல்லம் (chellam), meaning "dear one, darling, beloved" — a long-standing South [Indian] endearment used for cherished [children] and, by extension, spouses and close kin. The terminal -s follows the English diminutive-affectionate pattern (compare Becks, Wills, Tom-s), producing a form that is softer and more intimate than its Tamil antecedent. Origin and usage. Coined in [2023] by the submitter, Arvind [Karthik] (Chennai, Tamil Nadu), as a personal term of endearment for his [wife]. The [word] has since expanded in sense from a simple endearment (sense 1 above) to denote a constellation of admired qualities in a woman (sense 2), and is also used attributively/adjectivally (sense 3), most frequently in the collocation chellslike behaviour, used to describe endearing or admirable actions. Linguistic interest. The formation is a contemporary example of South [Indian]-English hybrid hypocoristic morphology: a Tamil affectionate base reshaped by an English diminutive suffix, producing a bilingual term of endearment that functions natively in both languages of the speaker's daily life. The submitter is aware that current evidence of usage is confined to a personal and familial context; this submission is offered as a record of the coinage and its semantic development, in line with the OED's interest in tracking emerging hybrid forms in World Englishes. Submitter. Arvind [Karthik], Chennai, India. First known [use]: [2023].
