Nouns with no meaning of their own: こと, もの, わけ, ところ and friends

You met the idea in the lesson on nominalizers: a clause plus a general noun makes a new noun. Japanese has about a dozen of these "formal nouns" (形式名詞). Each one is a noun that has lost most of its meaning, so it can sit after any clause and add one specific shade.

Because they all work the same way (clause + noun), you can learn one pattern and read them all.

Here is what each one adds.

ところ combines with tense to give different stages:

わけ gives the logical conclusion: "so that means...", or in the negative, "it doesn't mean that...".

Hear this in anime as 「そういうわけか」("so that's how it is").

ため has two jobs:

• Purpose: 勉強するために (in order to study)
• Reason (formal): 雨が降ったため (because it rained)

For purposes you can also use the ように pattern, which is about a state rather than an act:

ために (deliberate action) vs ように (hoped-for state).

もの at the end of a sentence expresses a reason with a pout, usually from children or women in casual speech (so もん):

ものだ states a general truth or fond remembrance:

When you meet an unfamiliar grammar pattern, ask three questions:

1. Is it clause + noun? (Check for こと, もの, わけ, はず, ところ, ため, ほう, うち, とおり.)
2. What is the plain-form tense of the clause? (dictionary = not yet, past = done.)
3. What does the noun contribute? (event, truth, reason, expectation, stage, purpose, comparison.)

That alone resolves most of the intermediate grammar you will meet.

Formal nouns build the logic of an argument. Spot each one and ask what it adds.

• Formal nouns follow a plain-form clause and add one shade of meaning.
• つもり = intend. ところ = about to / doing / just done. わけ = so it follows. ため = purpose / reason.
• はず = should. ほう = comparison. うち = while. とおり = just as.
• When stuck, ask: clause + noun? what does the noun add?
