Alternative vs alternate
British English and American English use these adjectives in slightly different ways, but the general consensus is the following:
- Alternative – A different option to the original one being considered, or a variation on the conventional
- Alternate – Every other one; occurring by turns
- He refused to consider an alternative route.
- She went to the gym on alternate Saturdays. (every other Saturday)
American English tends to accept ‘alternate’ as a synonym for ‘alternative’, but British English is less forgiving.
For the sake of completeness:
- The verb ‘to alternate’ means to go from one to the other, e.g. “He alternated between the two options.”
- “Alternative” can also be a noun, with the same meaning as the adjectival form, e.g. “No alternative was offered.”
Crevice vs crevasse
These two words aren’t a million miles apart from each other in meaning, but they are not interchangeable.
- Crevice – A narrow opening caused by a crack (either physically, as in a rock, or figuratively)
- Crevasse – A very large opening in the Earth’s surface or a glacier
- Megan squeezed through the crevice in the rock.
- The crevasse in the glacier was 20 metres across.
Extravert vs extrovert
This is such an interesting one. In short, ‘extravert’ is the original spelling (due to its roots in Latin), but as ‘extrovert’ has been adopted due to it often sitting alongside the correctly spelt ‘introvert’, the ‘o’ spelling is now accepted and is, in fact, the principal spelling in most dictionaries (e.g. Merriam-Webster’s Collegiate Dictionary, Oxford Dictionary for Writers and Editors).
The original ‘extravert’ tends to be used in psychological literature. For example, the Myers-Briggs test labels people as ‘extraverts’ or ‘introverts’. (By the way, I’m an INFJ-T – Advocate. What are you?)
- My daughter has always been an extrovert, but my son is more of an introvert.
- Jung defined the term ‘extravert‘ as someone who focuses their energy on the outer world.

- Leach – To drain or empty, often into surrounding material
- I found a leech in my pond.

Principal vs principle
- Principal – As an adjective, this means ‘main’, ‘primary’ or ‘chief’. As a noun, it can refer to a person in a position of authority, often in a school (US English), or college/university (British English). It can also be used to refer to an amount of money, meaning the same as ‘capital’. There are other meanings, all of which are covered well by Collins Dictionary, for both US and British English.

Damp squid vs damp squib
Here’s the one you’ve been waiting for.
I think this expression is particular to British English, but let me know if you live in another English-speaking country and use it. It doesn’t really belong on this particular list of commonly confused English words, as there is a right and a wrong answer.
The rest of the words on this page are all correct, but are often used in the wrong context, except for ‘extravert/extrovert’). However, the incorrect version is soooo frequently used that I feel it’s on the verge of being accepted as a correct alternative, if it hasn’t already been.
The correct expression is ‘a damp squib’ and means that something has turned out to be far less impressive than planned or expected. A squib is a small firework or explosive that, when damp, fails to go off with a bang.
- The book launch went off like a damp squib.
- Her party was a bit of a damp squib.
Squid, on the other hand, are always damp.'Damp squib' not 'damp squid'. A squib is a type of firework best used dry. Squids, on the other hand, are always damp – 8 commonly confused English words and how to use them Click To Tweet
