意向形: meaning, usage and examples
意向形 means: Verb Volitional-form.
How to form it
Group 1: -u -> -ou (書く -> 書こう) / Group 2: -る -> -よう (食べる -> 食べよう) / する -> しよう / 来る -> 来よう (こよう); polite: <Verb ます-stem> + ましょう
Examples
飲もう、食べよう、しよう、来よう
[Volitional-form] of drink, eat, do, come
今日は早く帰ろう。
Let's go home early today.
一緒に昼ご飯を食べよう。
Let's have lunch together.
来年、日本へ行こうと思っています。
I'm thinking of going to Japan next year.
疲れたね。ちょっと休もう。
That was tiring. Let's take a short break.
When to use it
The volitional form is the plain version of ましょう. Use it to suggest doing something together ("Let's...": 一緒に食べよう) or to talk to yourself about what you will do ("I think I'll...": もう寝よう). With と思っています it states a plan: 日本へ行こうと思っています (I'm thinking of going to Japan).
Nuance
On its own it is casual, used with friends and family. Use ましょう in polite speech. ようと思う is polite enough with です/ます (と思っています) and sounds softer than つもりです. As a question (行こうか) it offers or suggests: "Shall we go?"
Compare
ようと思う vs つもり: 行こうと思っています is a plan you are considering, 行くつもりです is a firmer intention. ましょう vs ませんか: 行きましょう suggests strongly, 行きませんか invites more gently and asks for the other person's opinion.
Tip: う-ending verbs need care: 会う -> 会おう, 買う -> 買おう. And remember 来る becomes こよう, not くよう.
