'integration-related' is a compound of 'integration' and 'related'. 'integration' originates from Latin, specifically the verb 'integrare' (from 'integer'), where 'integer' meant 'whole'. 'related' originates from Latin, specifically the past participle 'relatus' (from 'referre'), where 're-' meant 'back' and 'ferre' (or 'ferre' as part of 'referre') meant 'to carry or bring'.

'integration' entered English via Latin 'integrare' and Medieval/Latin technical use and became the modern noun 'integration' in Middle/Modern English. 'relatus' led to Old French and Middle English forms of 'relate' and its past participle 'related' became the modern adjective. The compound 'integration-related' formed in modern English by joining these two existing words to express connection to the concept of integration.

Initially, Latin roots conveyed the ideas 'whole' (for 'integration') and 'brought back/carried' (for the root of 'related'); over time 'integration' evolved to mean 'combining parts into a whole' and 'related' to mean 'connected to', so the compound now means 'connected to or concerning integration'.
