pro-immigration

The word is a modern English compound formed by directly attaching the Latin prefix "pro-" to the existing noun "immigration." The prefix "pro-" originates from the Proto-Indo-European root per- (forward, through), which in Latin solidified as a preposition and prefix meaning "for" or "in front of." The core noun "immigration" entered English in the 17th century from Latin, describing the action of coming to live permanently in a foreign country. Therefore, "pro-immigration" logically constructs its meaning as "in favor of the act of moving into a new country," reflecting a straightforward and transparent morphological process where an ancient directional prefix is applied to a later Latinate term to express a contemporary political or social stance.

Structure: pro (in favor of) + immigration (the act of moving to a new country) - pro: Latin origin, a prefix meaning "in favor of," "forward," or "for." - immigration: From Latin immigrare (to move into), composed of in- (into) + migrare (to move). The functional role is the core noun to which the prefix is attached.
