How to spell: words ending in -ly, -ely and -lly

Do you ever have problems spelling words ending in -ly?

If you do, you’re not alone. Adverbs such as definitely, probably, absolutely, likely, reasonably and hopefully often cause problems when it comes to spelling. We often ask ourselves the same questions:

Is it -ly or -lly?
Do we write -ely, or just -ly?

Normally we just add -ly to an adjective to get the adverb: quick becomes quickly, dangerous becomes dangerously.

The problem is when an adjective ends in -e or -le. What do we do in such cases? Do we keep or remove the ‘e’ before adding ‘ly’?

These short and simple rules should help you.

Forming adverbs from adjectives ending in -e, -l and -le
When an adjective ends in -e, we simply add ly to form the adverb:

polite » politely,
definite » definitely,
absolute » absolutely,
complete » completely.
Be careful when an adjective ends in -le. We remove the e and add y to form the adverb:

probable » probably,
possible » possibly,
terrible » terribly,
reasonable » reasonably.
Don't be confused by adjectives that end in -l. Simply add ly and the adverb will then end in -lly:

hopeful » hopefully,
beautiful » beautifully,
helpful » helpfully,
careful » carefully.

    You can add
    “when an adjective ends -y, We change the -y to -i and add -ly to form the adverb.”
    Example:
    Easy => Easily
    Lazy => Lazily

    What about words like automatic, which get turned into automatic + “ally”? Is there a rule for those?

    • Stuart Cook - March 2, 2014, 10:29 pm Reply

      For adjectives ending -ic, we simply add -ally to form the adverb:
      economic ➝ economically,
      dramatic ➝ dramatically,
      classic ➝ classically, etc.

        Thanks!

          We add double suffix al & ly (economic => economical => economically) and not add ally 🙂

      What about
      True. Truly??

  5. Eli - November 13, 2014, 1:53 pm Reply

    What about words that end -lly (eg: tally, jolly) and words that end -lley (eg: valley, trolley): is there a rule to help decide whether it should be -lly or -lley?

    • Richard Coe - July 1, 2016, 1:18 pm Reply

      These are nouns, so doesn’t apply.

    Clear and helpful, thanks for this great site.

    For Eli
    Eli this is a discussion about changing adjectives to adverbs so from your examples that would just be “jolly” (the nouns valley and trolley follow the usual rules for nouns ending in ey – just add s)
    You’re right Eli “jollily or sillily ” would be difficult to say so we avoid it .
    (You can say “It was done in a silly/jolly way” if you must describe an action using these kinds of adjectives)

    Please how about a words like absolutely?

    • Anonymous - October 8, 2015, 4:38 am Reply

      Absolutely is already an adverb. The adjective is absolute

  8. Anonymous - November 28, 2015, 7:00 pm Reply

    Would there be a situation where an adverb would end in ley rather than ely?

    Thanks

    But what about basic = basic’al’ly

    • ena - June 5, 2018, 12:16 am Reply

      See above the rule for adjectives ending in -ic.

  11. sherdeis - May 14, 2017, 10:17 am Reply

    Rule for words ending in double-vowel then ?
    E.g. shortsounding wool becomes wolly, long-sounding cool becomes coolly but long-sounding steel becomes steely.

    Why Truly not truely?

    • simranjit kaur - May 25, 2019, 1:16 am Reply

      it is actually True, so basically we cancel -e and add + ly (truly). Wallahhhh aghhh, thank you so much this is life for me I always have trouble spelling these stuff.
