The word or phrase
Why it’s nonstandard
Say this instead
The prefix Ir- and suffix -less both mean ‘without,’ making ‘irregardless’ a one-word double negative.
Impact (as a verb)
Shortening ‘has an impact on’ to ‘impact’ is a sign of laziness. Some nouns just aren’t ready to be verbs.
Chopping the -ion suffix off a noun doesn’t always make it a verb. ‘Converse’ says the same thing in fewer letters.
The intended phrase comes from the French ‘en route,’ meaning ‘on the way.’
Could of, would of, should of
In speech, few people can hear the difference between ‘could have’ and ‘could of.’ In writing, ‘could of’ is noticeably wrong.
Could have, would have, should have
‘Importantly’ is an adverb, as is ‘more importantly.’ When a word modifies an entire independent clause, rather than just the verb, it acts as an adjective. So when people use ‘more importantly’ to begin a sentence, they’re using an adverb to do an adjective’s job. Use the adjective form instead.
‘Try’ is almost always a transitive verb, meaning you have to try ‘something,’ whether it be a noun, gerund, or infinitive verb. ‘And’ is a coordinating conjunction; it doesn’t work.
One of the only
This phrase is used when talking about one member of a small group. ‘Only’ means ‘excluding all others,’ while ‘few’ means ‘a small group.’ Which sounds more appropriate?
