The truth, THE WHOLE truth, and nothing but the truth!

Meaning: Whole means todo, entero, la totalidad. 

Pronunciation: The W is NOT pronounced, so it rhymes with soul (alma). If you get the wrong pronunciation, people will probably think you're talking about a pared: wall. Whole has exactly the same sound as the word HOLE (=agujero).

Usage: whole + countable nouns.

Examples: the whole day, the whole week, the whole morning, the whole school, the whole country, the whole world, the whole class, the whole family.

Advanced points: 

1.It is most often found with singulars. If it goes with a plural noun, the meaning is not the same as ALL:

All the villages were destroyed in the war. (todos los pueblos)

Whole villages were destroyed in the war. (pueblos enteros)

2.Before proper nouns (nombres propios), use the whole of:

The whole of Spain was in a state of shock.

Remember: ¡No suena como WALL ni parecido!
