Last vs. Lastly – Which is Correct?
Both last and lastly are correct, but they serve different purposes. Last usually introduces the final item in a sequence or means most recent, final, or continuing. Lastly is an adverb meaning “finally” and typically signals the final point in an organized list, particularly in formal writing and presentations often.
Last or Lastly – Which is Correct?
Last and lastly are both correct American English words, but they are not interchangeable in every sentence. Last can function as an adjective, adverb, noun, or verb. It may describe the final item, refer to the most recent time, or mean to continue for a period of time.
Lastly is an adverb used mainly as a transition meaning “finally” or “as the final point.” It is especially common when presenting several reasons, instructions, or arguments. In many contexts, last sounds more natural and concise, while lastly has a more formal or structured tone.
Use last for meanings such as “final,” “most recent,” or “continue.” Use lastly when you are deliberately marking the final point in a series.
The Best Trick to Remember the Difference
Use the “final item versus final point” test. If you are naming the final person, object, event, or time, choose last: “She finished last,” “last month,” or “the last chapter.” If you are introducing the final argument or step in an organized explanation, choose lastly: “Lastly, check your spelling.”
A useful swap test is this: if finally fits naturally as a transition, lastly may work. If you mean “the one at the end” or “the most recent,” use last.
| Word | Part of Speech | Meaning | Example |
|---|---|---|---|
| last | Adjective, adverb, noun, or verb | Final, most recent, or continuing | We visited the last museum on the list. |
| lastly | Adverb | Finally; as the final point | Lastly, review the conclusion. |
How to Use Last
Last has several meanings and grammatical functions. As an adjective, it identifies the final item in a sequence or the most recent occurrence: “the last bus” or “last Friday.” As an adverb, it can describe position or time: “Who arrived last?” or “When did you last call?”
Last can also function as a noun, as in “The last of the guests left,” and as a verb meaning to continue: “The meeting lasted two hours.” It is common in casual, professional, and academic English.
Example 1: The last train leaves at midnight.
Example 2: I last spoke with her in June.
Example 3: These batteries should last for several months.
Etymology of the word Last
Last comes from Old English words related to latest and final. Its verb sense, meaning “to continue,” developed from an older Germanic root associated with remaining or enduring. Over time, the word acquired its modern meanings involving sequence, time, endurance, and final position.
How to Use Lastly
Lastly is an adverb that introduces the final point in a sequence. It commonly appears alongside transitions such as firstly, secondly, and thirdly. For example: “Firstly, identify the problem. Secondly, compare the options. Lastly, choose a solution.”
The word is grammatically correct, but it can sound formal or slightly stiff in everyday conversation. In many situations, finally or simply last is more natural. Do not use lastly to mean “most recently”; say last week, not “lastly week.”
When choosing a formal transition, confirm the spelling with Finally vs. Finaly before replacing lastly.
Example 1: Lastly, make sure every source is cited.
Example 2: The proposal is affordable and, lastly, easy to implement.
Example 3: Lastly, I would like to thank everyone who contributed.
What are the different forms of Lastly?
Lastly is an invariant adverb, so it does not change form for tense, number, or comparison. There is no standard form such as lastlier or lastliest. Related words include last, lastly, and final, but these words do not always perform the same grammatical role.
Etymology of the word Lastly
Lastly is formed from last and the adverb-forming suffix -ly. The suffix gives the word the meaning “in a last or final manner.” Its use as a transition developed from the idea of presenting the final point in a series.
