A party or entity that is allied with another; a state or power in an alliance.
From Old French 'alliant' (an ally), present participle of 'alier' (to ally). Related to French 'allié' (allied).
The word 'alliant' appears in historical treaties and diplomatic documents but has been overshadowed by 'ally'—yet it subtly suggests a more formal, contractual relationship than a casual ally.
