It's used correctly. Got is not necessary and some consider using it improper.
Without the contraction, it would read:
'We have to gather more information before we can finish the project'. which is right.
Here are some common errors:
1. Accept/Except- Although these two words sound alike (theyre homophones), they have two completely different meanings. Accept means to willingly receive something (accept a present.) Except means to exclude something (Ill take all of the books except the one with the red cover.)
2. Affect/Effect- The way you affect someone can have an effect on them. Affect is usually a verb and Effect is a noun.
3. Alright- If you use alright, go to the chalkboard and write Alright is not a word 100 times.
4. Capital/Capitol- Capitol generally refers to an official building. Capital can mean the city which serves as a seat of government or money or property owned by a company. Capital can also mean punishable by death.
5. Complement/Compliment- I often must compliment my wife on how her love for cooking perfectly complements my love for grocery shopping.
6. Comprise/Compose- The article Im composing comprises 32 parts.
7. Could Of- Of the 32 mistakes on this list, this is the one that bothers me most. Its could have not could of. When you hear people talking, theyre saying couldve. Got it?
8. Desert/Dessert- A desert is a hot, dry patch of sand. Dessert, on the other hand, is the sweet, fatty substance you eat at the end of your meal.
9. Discreet/Discrete- We can break people into two discrete (separate) groups, the discreet (secretive) and indiscreet.
10. Emigrate/Immigrate- If I leave this country to move to Europe, the leaving is emigrating and the arriving is immigrating.
11. Elicit/Illicit- Some people post illicit things on message boards to elicit outrageous reactions from others.
12. Farther/Further- Farther is used for physical distance, whereas further means to a greater degree.
13. Fewer/Less- Use fewer when referring to something that can be counted one-by-one. Use less when its something that doesnt lend itself to a simple numeric amount.
14. Flair/Flare- A flair is a talent, while a flare is a burst (of anger, fire, etc.)
15. i.e/e.g- I.e. is used to say in other words. E.g. is used in place of for example.
16. Inflammable- Dont let the prefix confuse you, if something is inflammable it can catch on fire.
17. Its/Its- Its= it is. Its=a possessive pronoun meaning of it or belonging to. Whatever you do, please dont use its.
18. Imply/Infer- A reader infers what an author implies. In other words, when you imply something, you hint at it. When you infer something, you draw a conclusion based on clues.
19. Literally- If you say His head literally exploded because he was so mad! then we should see brains splattered on the ceiling.
20. Lose/Loose- If your pants are too loose you may lose them. That would be almost as embarrassing as misusing these two words.
21. Moral/Morale- Morals are something you want to teach your kids. If your teams morale is low, you need to do something to boost their confidence.
22. Percent/Percentage- The word percent should only be used when a specific number is given. Percentage is more of a general term.
23. Stationary/Stationery- You are stationary when you arent moving. Stationery is something you write on.
24. Then/Than- Then is another word for after. Incidentally, the word then makes for boring writing. Than is a comparative word (e.g. I am smarter than you).
25. There/Their/Theyre- There are few things as frustrating as when I look at my students writing and theyre misusing these words in their writing.
26. Unique- Something cant be kind of unique or even very unique. Its either one-of-a-kind or it isnt. There is no in between when it comes to unique.
27. Your/Youre- If I had a nickel for every time I saw this one
yeah, you know the rest. Your shows ownership and youre is a contraction meaning you are. Get it right.
28. To/Too/Two- Two is a number. To is used in instances such as, I am going to the store. If you are supposed to use the word too, try inserting the word extra or also. If one of those fits, you need to also add the extra o to make too.
29. Lie/Lay- After you lay the books on the table, go lie down on the couch.
30. Sit/Set- Set your drink on the table and sit in your chair. Got it?
31. Whose/Whos- Whose is the possessive form of who. Whos is a contraction meaning who is.
32. Allude/Elude- When someone alludes to something in conversation (indirectly references), if you arent paying attention the meaning may elude you (escape you).
