In other words, don’t use the word “down” after a noun.

You can’t say:

Weight down  (Instead, say “lose weight.”)

Speed down  (Instead, say “slow down.”)

But, you can say:

Look down on

Move down

Pat down

Run down

Scale down

Settle down

Sit down

Slow down

Stand down

Step down

Tie down

(To be) down

So, be careful and don’t down your nouns!

Use “the” before a noun when…

• the listener knows the exact thing you are talking about “The speech was really long.” (The listener knows the speech you are talking about.) “The car that drove by was speeding.” (The listener saw the car.)
• there is only one in the whole world. “The Internet has made my life easier.” (There is only one Internet.)
• the noun represents a place in a community that everyone knows or shares. “I went to the bank.” “I went to the grocery store.” “I went to the library.” (Even if you don’t go to the same back, you should still use “the.”)

Don’t use “the”  when…

• the noun is a proper noun (a name, city, company). “I searched for it on Google.” “I live in California.” (However, we DO use “the” when referring to “the United States.”)
• you use a pronoun with the noun. “I washed my car.” “Your pen is on my desk.”

Use “a” or “an” before a noun when…

• you do not define the noun. The noun is general.  “I saw an interesting website today.” (You don’t explain which website.) However, when you talk about this same website again, you will say, “The website was interactive.” (Now, you use an article because the listener knows that you are talking about the website you saw earlier.)
• the noun is one of many. “I ate an apple for lunch.” (There are many apples, and you ate one.)

Use “an” when the noun that follows it starts with a pronounced vowel: we say, “an underachiever” but  “a university.”  The u in underachiever is pronounced as a vowel, but the u in university is pronounced with a “yu” sound.

Don’t use “a” or “an”  when…

• the noun is a plural. “Universities are getting more an more expensive these days.”
