A person or entity that forms an alliance with another; one who allies themselves with a partner or group.
From 'alliance' + '-er' (agent noun suffix, indicating one who performs an action). Parallel formation to similar agent nouns like 'commander' or 'learner.'
The term 'alliancer' is so rare it barely exists in modern usage, but it perfectly captures the idea that forming alliances is an active, intentional role—you're not just a party to an agreement, you're an alliancer.
