“A” and “An”
Use “a” before a word that begins with a consonant sound, and use “an” before a word that begins with a vowel sound. “a dog chased me”, or “an apple fell on me”.
Adjectives before Nouns
For people who speak a Romance language like Spanish, French, Italian, or Portuguese there is a tendency to place the adjective after the noun. In English the adjective always comes before the noun. For example, “the big dog” is correct but “the dog big” is incorrect.
Do/Don’t and Does/Doesn’t
You use “do” and “don’t” for first person singular, second person singular and plural, and third person plural. For example “I do/I don’t”, “you do/you don’t”, and “they do/they don’t”. Use “does” and “doesn’t” for third person singular. “He does/she doesn’t”.
Lend, Loan, and Borrow
In some languages the same word is used leaving only the “to” and “from” to determine who gives and who receives, but in English different words are used for the giver and the receiver. I “loan” to you and you “borrow” from me. The person who borrows is the “borrower” but the person who loans is the “lender”. Loan and lend mean the same thing when they’re referring to money or objects, but when you use the word figuratively you use “lend” but never “loan”. For example:
“lend me a hand” (give me some help)
“lend me your ears” (listen to me)
In other languages like Spanish and Portuguese it’s considered okay to say “I don’t need no more” but it’s incorrect grammar in English. Double negatives are used sometimes in songs or poetry but in everyday speech they’re considered wrong.
Past Tense Issues
Correct: I did that, I have done that, I should have done that, I went, I have gone, you took one, you have taken one, he made it, he has made it, they wanted to go, they have wanted to go.
Incorrect: I have did that, I done that, I has done that, I has did that, I should have did that, I have went, you has took one, you taked one, you has taken one, he maked it, he have made it, they has wanted to go.
Me, Myself, and I
Use “me” as the object in a sentence. “He gave it to me”, or “For me, it’s difficult”.
Use “myself” when you are the subject and the object, or for emphasis. “I hurt myself”, or “I do that a lot myself”
Use “I” as the subject. “I gave it to him”, or “I think you’re right”
In, On, and At
Use “in” for an enclosed area like a room.
Use “on” for a flat surface like a floor.
Use “at” for a location like a building.
