'temporarily-stationed' is a compound formed from 'temporarily' and 'stationed'. 'Temporarily' derives from Latin 'temporarius' (via Old French/Latin influence), where 'tempus' meant 'time'. 'Stationed' comes from Latin 'stationare'/'statio' (via Old French and Middle English), where 'stare' meant 'to stand'.

'temporarily' originates from Latin 'temporarius' → Old French/Latin forms → Middle English 'temporary' → modern English 'temporarily'. 'Stationed' developed from Latin 'statio'/'stationare' → Old French 'estacion'/'estacioner' → Middle English 'station'/'stationen', eventually forming the past participle 'stationed' in modern English. The compound use as a hyphenated adjective (e.g., 'temporarily-stationed') reflects modern English compounding conventions for clarity.

Initially, the elements referred separately to 'time' ('temporary') and 'standing/being posted' ('stationed'); over time the compound came to specifically mean 'placed or assigned to a location for a limited time' and is used as an adjectival description.
