The Origin of Mistakingly or Mistakenly
To understand why this confusion exists, we need to look at word history.
Root word: Mistake
Both mistakenly and mistakingly come from the verb mistake, which entered English from Old Norse mistaka, meaning “to take in error.”
How adverbs are formed
In English, adverbs are often formed by adding -ly to adjectives.
- Mistaken (adjective) → mistakenly (adverb)
- He was mistaken. → He was mistakenly (in his belief)
This pattern is natural and common.
Why “mistakingly” appeared
Mistakingly is formed from the verb mistaking, not the adjective mistaken.
- Mistake → mistaking → mistakingly
This structure is less natural in English. Over time, writers preferred mistakenly because it sounds smoother and fits normal grammar rules.
Historical usage
- Mistakenly has been common since the 16th century.
- Mistakingly appeared later and never gained wide acceptance.
That is why modern English favors mistakenly almost everywhere.
