よEmphasis (Sentence ending particle)

よ is classified as a sentence ending particle in Japanese. In most cases, it is used to convey new information to the listener, or just to add a bit of emphasis. Like most sentence ending particles, it is simply added to the end of almost any sentence.

Despite the standard use of よ being to convey new information, it is also very regularly paired with ね, to convey the meaning of 'right?!'. This more literally means something closer to 'I think (A), and I bet you think (A) too!'.

Caution

Did you notice that there is a だ after the noun, but not the い-Adjective? This is not a unique rule for よ, but just one of the regular conjugation rules introduced in the lessons for い-Adjectives and な-Adjectives. It is also acceptable to use ですよ after either type of adjective (or noun).
