Commonly confused words, with the rule and a memory trick for each

A while (two words) is a noun phrase, an article plus a noun, so it can follow a preposition such as for or in: for a while, in a while. Awhile (one word) is an adverb meaning for a time, so it describes a verb and does not follow for: rest awhile.

Remember: After for or in, split it: for a while. If it sits right after the verb with nothing in between, one word works: stay awhile.

• –It took a while to learn the new scheduling system.
• –Rest awhile before the second half of the shift.

Adverse means unfavorable or harmful and describes conditions or effects: adverse weather, an adverse reaction. Averse means reluctant or opposed and describes a person: averse to risk.

• –I could have taken the earlier bus.
• –We should have logged the call before the shift ended.

Into (one word) is a preposition that shows movement to the inside of something, or a change: walked into the office, turned into a problem. In to (two words) is when in belongs to the verb (log in, turn in, hand in, check in) and to belongs to what follows: log in to the portal, turn the form in to HR.

US vs UK: US: judgment. UK: judgement (judgment in legal writing).

Lay means to put or place something, so it needs an object: you lay the file down. Lie means to rest or recline, with no object: you lie down. The trap is the past tense, because the past of lie is lay. The forms: lay, laid, laid, laying; lie, lay, lain, lying.

Led is the past tense of the verb lead (to go first, to guide). Lead, pronounced “leed”, is the present tense. Lead pronounced “led” is the metal, which is why the past tense gets misspelled.

• –She led the morning huddle while the manager was out.

• –Please copy Dana and me on the reply.
• –I set up the new workstation myself.

Passed is only a form of the verb pass, its past tense and past participle: she passed, has passed. Past is everything else: a noun (the past), an adjective (past clients), a preposition (walk past the desk) or an adverb (drove past).

That introduces a clause the sentence needs to make its point, with no commas: the files that are overdue. Which introduces extra information you could lift out, set off with commas: the files, which are in the cabinet, are overdue.

Remember: If you can drop the clause and keep the point, use which with commas.

• –Return the badges that were issued to temps.
• –The new scanner, which arrived Monday, is already in use.

Their shows ownership: their desks. There points to a place or starts a sentence: over there, there are. They’re is short for they are.

• –Their shift ends at seven.
• –The spare chargers are over there, and they’re labeled by department.

Who is a subject, the one doing the action, like he or they. Whom is an object, the one receiving the action or following a preposition, like him or them. The choice depends on the pronoun’s job inside its own clause, not the whole sentence.
