# Different ways to show intention to do something

How can one say "I am going to", express intention to do something in the future. I know some expressions such as:

たいと思う - 　I'm going to/ I want to

ましょう - I will/ Why don't I

しようと思う　- I think I will

しようとする - I'll try to

つもり - I plan to

する予定がある - I have plans to

する気がある - I feel like

ことにする - decide to

まいとする　- I'll try not to

まいと思う - I think I won't

Do I understand what they mean correctly? Which are better to use when? What is the difference between similar expressions (予定　and　つもり) ?

• I think you might be better off breaking up this question into smaller (slightly more focused?) questions. :) In general, the meanings seem correct (except, I'm not quite sure about that しょうと思う usage...) but anyway, if the question is broken up, it can generally help for getting answers. – summea Mar 13 '12 at 22:59
• @summea, I meant しようと思う, mistyped, sorry about that. As for breaking up the question, I think I'll wait a bit. – Velenir Mar 14 '12 at 3:18

Your definitions were mostly OK I think.

I'm not an expert on grammar, so take this as a temporal answer until other people answer, but my interpretations thus far are...:

• ～たいと思う means "I think I'd like to...":

本を読みたいと思う "I think I'd like to read a book"

• ～ましょう means "let's do..." (polite form):

• ～しようと思う means "I think I'll...":

本を読もうと思う "I think I'll read a book"

• ～しようとする means "I'll try to..." as you said:

本を読もうとする "I'll try to read a book"

• ～するところ means "I'm about to..."/"I'm at the point of..." or "place for (do)ing...":

• ～つもり means "I intend to", slightly less formal than ～予定がある I think and is less likely to be used in business etc:

本を読むつもりだ "I intend to read a book"

• ～する予定がある "I have plans to" as stated:

本を読む予定がある "I have plans to read a book"

• ～する気がある "I am of a mind to":

本を読む気がある "I am of a mind to read a book"

• I think ～ことにする translates differently depending on the context, but that it generally means "(will) go with (do)ing...":

今週こそは本を読むことにする "I will go with reading a book this week"

I'm not sure about ～まいとする and ～まいと思う. I think the difference between ～予定がある and ～つもり might need it's own question.

• I thought ～たいと思う was "I think I want to.." – dotnetN00b Mar 14 '12 at 5:56
• @dotnetN00b I think both "I think I want to..." and "I think I would like to..." would work, but I'm not sure. Space ALC defines it as "be inclined to" among other definitions. – cypher Mar 14 '12 at 6:14
• My dictionary states that ~まいと思う is the negative form of ~ようと思う – Ambo100 Dec 3 '18 at 22:39
