Select the word that is spelt INCORRECTLY.

Concept

To find a misspelt word, recall the standard dictionary spelling of each word and compare it letter by letter with the form shown. A word is wrong if even one letter is added, dropped, or changed from its accepted spelling. Pay special attention to the number of repeated consonants at the end of a word, a common spelling trap.

Applying it here

Check each given form against its accepted dictionary spelling:

• “Excel” → matches the dictionary form (to do extremely well).

• “Excess” → matches the dictionary form (an amount beyond what is needed).

• “Access” → matches the dictionary form (the right or means to approach/use something).

• “Expell” → does NOT match; the accepted spelling is “expel”, with a single final “l”.

Cross-check

The verb “expel” keeps one “l” in its base form; the second “l” appears only when a suffix beginning with a vowel is added (expelled, expelling). The bare form written with two “l”s is therefore the incorrectly spelt word.

Correct spelling: expel.
