Grammar

Put grammar explanations here to save writing them out over and over. Feel free to add any, or rewrite the explanations to fit what you're using them for.

か・き・く・け・こ
かもしれない Means 'might, maybe'. Shows a lower level of certainty/accuracy than other words with a similar meaning (だろう shows more certainty, and にちがいない the highest level of certainty). It's for judgements based on logical reason, rather than perceptual evidence (for which you'd use ～そうだ).

さ・し・す・せ・そ
さ Used to get the listener's attention, a little 'fillerish' maybe. It can come after 'filler' words (じゃあさ、あのさ), or other phrases (でもさ、昨日さ、お前さ、それでさ). Used in casual conversations. Sometimes used so much that it's used after almost everything (あのさ、俺さ、昨日さ、新宿でさ…). (Disclaimer: this is exaggeration.)

ッス A slurred version of です, this is associated with jocks or sports types as a casual way to show respect.

た・ち・つ・て・と
～たい Shows the speaker's desire or wish to do something.

ＡたらＢ A conjunction meaning 'when, if, after'. 'A' describes some condition, and 'B' some event that occurs when that condition takes places.

～って 1) A casual form of と used to quote. 2) A casual form of とは. 3) Used to assert or emphasise the speaker's feelings.

～とけ A casual contraction of ～ておく. おけ is the imperative (command) form of おく.

～ていいですか Used to ask permission, 'may I...?' This construction is formed by using the て form of the verb.

～ておく This means to do something in advance and leave in that state for the future.

な・に・ぬ・ね・の
ね A particle that softens a request or demand.

は・ひ・ふ・へ・ほ
～への～ A combination of へ, which means 'to', and の, which is used to join two nouns. Together they mean 'to', as in “a message to you, a letter to him, etc.” にの, however, is grammatically incorrect and cannot be used.

ま・み・む・め・も
も A particle meaning 'as well, also, too' (as in this example, 'me too').

や・ゆ・よ
よ A particle used to show emphasis or add stress.

わ・を・ん
（～んな） A casual contraction of ～るな, here the full form is あせるな. The な used here expresses prohibition, a negative command ('don't ~').
