The Origin of Acquirer or Acquiror

Both words come from the Latin verb acquirere, meaning “to gain” or “to obtain.”

• Acquire → verb
• Acquirer / Acquiror → noun (the one who acquires)

The spelling difference exists because English forms nouns in two common ways:

• -er (writer, buyer, owner)
• -or (actor, donor, creditor)

Over time, -er became more popular in modern English, while -or remained common in legal and formal contexts. This is why acquiror still appears in contracts and court documents.
