'strongly-bonded' originates from the combination of 'strongly' and 'bonded', where 'strongly' is derived from 'strong', meaning 'having great physical power', and 'bonded' is the past participle of 'bond', meaning 'to join securely'.

'strongly-bonded' evolved from the Middle English word 'bond', which came from the Old Norse 'band', meaning 'a tie or binding'.

Initially, 'bond' meant 'a tie or binding', but over time it evolved to include the concept of a strong connection or attachment.
