What does complained mean?
To complain is to express dissatisfaction, discomfort, or grievance — whether about faulty goods, poor service, unfair treatment, or physical pain — and 'complained' is its past tense, marking that such an expression has already taken place. The word carries a mildly negative connotation in everyday speech: habitual complainers are often seen as tiresome, yet complaint itself serves an essential social function, alerting businesses, officials, and doctors to genuine problems. In medical settings, a patient who 'complained of' chest pains is offering clinically useful information rather than mere grumbling. Derived from the Latin 'complangere', literally 'to beat together' in lamentation, the word has long been bound up with expressions of suffering. From consumer grievances and workplace disputes to courtroom testimony and doctor's notes, 'complained' remains one of English's most versatile verbs for voicing displeasure.

Etymology of complained
The verb derives from Middle French 'complaindre', which came from Late Latin 'complanctere', from Latin 'com-' (together) plus 'plangere', meaning to strike or beat — originally describing ritual breast-beating as an outward sign of grief. The root 'plang-' also underlies English words such as 'plaintive', 'plaintiff', and 'plague'. The sense shifted over time from loud lamentation toward more ordinary verbal protest, settling into its modern use by the late medieval period.
