What are they?

In English, we often use two nouns together to name something.
The first noun describes or gives more information about the second noun — it works like an adjective.

Example:

• chocolate cake = a cake made with chocolate
• car key = a key for a car

Word Order Difference

In Portuguese, we usually say:

X de Y → bolo de chocolate

In English, we flip the order:

Y + X → chocolate cake

Think of it as “turning the phrase around.”

Important Notes

✅ The first noun is usually singular, even when it refers to something plural:

• a shoe store (not shoes store)

✅ If we use nouns that are always used in plural forms (such as shoes, glasses, gloves, etc.) as a modifier for another noun, we have to use them in the singular form:

• His shoe size is 44.

Shoe is a singular form of the normally plural word shoes used to modify the noun size.

✅ Sometimes two nouns become a compound noun — a single concept that can be written as:

• one word (toothbrush, toothpaste, bedroom, policeman)
• two separate words (coffee cup, police station)
• or hyphenated (mother-in-law, check-in, 15-year-old boy)

There’s no fixed rule for which form to use — it’s based on common usage.
👉 When in doubt, check a dictionary to see if it’s one word, two words, or hyphenated.

Common Mistakes for Portuguese Speakers

salad potato ❌
potato salad ✅

cup wine ❌
wine cup or wine glass ✅

The first noun always comes before the main noun and without “of”.
We only use “of” for possession or abstract ideas (the color of the sky, a friend of mine).
