<div class='writeup-body'>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.<ul class='writeup-examples--holder'><li class='writeup-example'><div class='writeup-example--japanese'>それは熱（あつ）いよ。</div><div class='writeup-example--english'>That is hot!</div></li><li class='writeup-example'><div class='writeup-example--japanese'>明日（あした）は雨（あめ）だよ。</div><div class='writeup-example--english'>It's going to rain tomorrow!</div></li></ul>Despite the regular use of よ being to convey new information, it is very regularly paired with ね, to convey the meaning of 'right?!'. Literally it means something closer to 'I think (A), and I bet you think (A) too!'.<ul class='writeup-examples--holder'><li class='writeup-example'><div class='writeup-example--japanese'>あれは先生（せんせい）だよね。</div><div class='writeup-example--english'>That over there is a teacher, right?</div></li><li class='writeup-example'><div class='writeup-example--japanese'>車（くるま）は高（たか）いよね。</div><div class='writeup-example--english'>Don't you think cars are expensive?</div></li></ul><div class='writeup-caution'><div class='caution-header'>Caution</div>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).</div></div>
