What is the difference between its and it’s?
Its shows possession (the cat licked its paw), while it’s is short for it is or it has (it’s cold today). The apostrophe always means it is, never belonging, which is the opposite of what many people expect.
Affect or effect, which do I use?
Affect is usually a verb meaning to influence (the weather affects my mood), and effect is usually a noun meaning the result (the weather had an effect on me). If you need an action word, it is almost always affect.
Why do I keep confusing since and for?
Because both talk about time, but differently. Use since with a starting point (since 2020, since Monday) and for with a duration (for three years, for an hour). Since answers from when; for answers how long.
