Synonym discussion
Sense: noun/1
All four refer to expressing unhappiness, but they differ in tone and register. 'Complaining' is the most neutral and formal of the group: you can complain to a manager, to customer service, or in a serious letter, and the word does not necessarily judge the speaker. 'Moaning' is informal and especially common in British English; it suggests low-stakes grumbling about everyday annoyances and often hints that the listener is bored of hearing it. 'Grumbling' describes muttered, half-hearted protest under one's breath, often without expecting anything to change. 'Whining' is the most negative: it pictures a high-pitched, childish, irritating tone, as a child might use to ask for sweets. Compare: 'I sent a complaining email to the airline' (serious), 'Stop moaning about the rain' (mild irritation), 'He kept grumbling about his back' (muttered), 'She is whining for ice cream again' (childish).

Etymology
Both the noun and adjective are present-participle forms of the verb 'complain', plus the ending '-ing'. The verb 'complain' came into Middle English from Old French 'complaindre', from Vulgar Latin 'complangere', built on Latin 'plangere' meaning 'to beat the breast' or 'to lament'. The original Latin sense pictured a person striking their chest in grief; the modern English meaning has cooled into the everyday act of saying something is wrong.
