The act of aligning or arranging things in a line; alignment.
From Old French 'aligner' (to align) + Latin '-tion' (action/result). The prefix 'a-' means 'to' and 'line' comes from Latin 'linea', meaning a thread or mark.
This older spelling of 'alignment' reminds us that English spelling wasn't standardized until the 1700s—the same action had multiple spellings depending on whether you learned from French or Latin sources.
