Noun + noun

 When putting nouns together, there are three common ways to do it in English:

1. Possessive (Genitive) form: One noun is used in the possessive form to modify the other noun.

Example: The dog's bark (the bark of the dog)

2. Preposition "of": A preposition "of" is used to connect the two nouns, with the second noun being the one that is modified.

Example: The color of the sky (the sky's color)

3. No linking word: Two nouns are used together without any linking word, and the first noun modifies the second noun.

Example: Football game (a game of football)

Here's a chart to show these different ways of putting nouns together:

Nouns	Possessive form	Preposition "of"	No linking word
Dog bark	The dog's bark	The bark of the dog	Dog bark
Sky color	The sky's color	The color of the sky	Sky color
Car engine	The car's engine	The engine of the car	Car engine
Coffee cup	The coffee cup's lid	The lid of the coffee cup	Coffee cup
Music player	The music player's volume	The volume of the music player	Music player
