'frequently-attached' originates from the combination of 'frequently,' derived from Latin 'frequentia,' meaning 'crowded or repeated,' and 'attached,' from Old French 'atachier,' meaning 'to fasten or join.'

'frequently' changed from the Latin word 'frequentia' to the Old French 'frequent,' and eventually became the modern English word 'frequently.' 'Attached' evolved from the Old French 'atachier' to the modern English 'attach.'

Initially, 'frequently' meant 'crowded or repeated,' and 'attached' meant 'to fasten or join.' Over time, 'frequently-attached' evolved to mean 'often connected or associated with something.'
