付せん means sticky notes or Post-it notes.

A very common kanji spelling is 付箋. In everyday writing, you may see:

• 付せん
• 付箋
• sometimes ふせん

In this sentence, it refers to sticky notes being used for some purpose, but they were not enough by themselves.

だけ means only or just.

So 付せんだけでは means:

• with only sticky notes
• if using only sticky notes
• sticky notes alone

The では adds the sense of in that case / by that means / under that condition.

So 付せんだけでは足りなかった means something like:

• Sticky notes alone were not enough
• Using only sticky notes wasn’t enough

This is a very common question.

Here, で shows the means or method:

• 付せんで = using sticky notes

Then は adds contrast or emphasis:

• 付せんだけで = with only sticky notes
• 付せんだけでは = with only sticky notes, at least / as for using only sticky notes, ...

So では often has a contrastive feeling. It suggests:

• using only sticky notes was not enough, so something else was needed

That fits perfectly with the second half:

• のりも使いました = I also used glue

足りる means to be enough or to suffice.

Its plain past negative form is:

• 足りなかった = was not enough / did not suffice

Breakdown:

• 足りる = to be enough
• 足りない = is not enough
• 足りなかった = was not enough

In this sentence, it means the sticky notes alone were insufficient for whatever the speaker was trying to do.

Because the speaker is talking about a completed situation in the past.

The sentence ends with:

• 使いました = used

So the speaker is describing what happened:

1. Sticky notes alone were not enough.
2. So they also used glue.

That is why 足りなかった is also in the past:

• it wasn’t enough

ので means because or so.

In this sentence:

• 付せんだけでは足りなかったので、のりも使いました。
• Because sticky notes alone were not enough, I also used glue.

Compared with から, ので often sounds a bit softer, more explanatory, and slightly more formal/polite.

So:

• 足りなかったので = because it wasn’t enough / since it wasn’t enough

Both can mean because, but they have slightly different tones.

• から can sound more direct, personal, or assertive.
• ので often sounds softer and more matter-of-fact.

So these are both possible:

• 付せんだけでは足りなかったので、のりも使いました。
• 付せんだけでは足りなかったから、のりも使いました。

The first one sounds a little more neutral and explanatory. In polite speech, ので is very common.

のり means glue or paste.

The particle も means also or too.

So:

• のりも使いました = I also used glue

The idea is:

• I used sticky notes.
• And I used glue too.

That も is important because it shows glue was added, not used instead of the sticky notes.

Japanese often leaves out the subject when it is obvious from context.

So the sentence does not explicitly say:

• I
• we
• he/she

But from context, English usually translates it as something like:

• I also used glue or
• We also used glue

This omission is completely natural in Japanese.

Another great question: Japanese often leaves out information that English would spell out.

In 付せんだけでは足りなかった, what was not enough is not directly stated. It could mean:

• sticky notes were not enough to attach something
• sticky notes were not enough for the task
• sticky notes alone were not enough to hold it in place

The listener is expected to understand the missing idea from context.

So literally it is just:

• With only sticky notes, it was not enough

English usually fills in the gap naturally.

Yes, in casual speech.

• だけでは = more neutral / written / careful
• だけじゃ = more casual, conversational

So you could say:

• 付せんだけじゃ足りなかったので、のりも使いました。

This is natural in speech, though mixing じゃ with 使いました still gives a slightly mixed casual-polite tone. That can happen in real conversation.

A fully careful version:

• 付せんだけでは足りなかったので、のりも使いました。

A more casual version:

• 付せんだけじゃ足りなかったから、のりも使った。

This is because 足りなかった is attached to ので, not ending the sentence by itself.

Japanese often uses:

• plain form before connectors like ので, から, けど, とき, etc.
• polite form at the end of the sentence

So this pattern is very normal:

• 足りなかったので、使いました。

Not:

• 足りましたので would mean something different
• 足りませんでしたので is possible, but often sounds more formal/stiff

Using plain form before ので and polite form at the sentence end is standard polite Japanese.

It breaks down like this:

• 付せんだけでは = with only sticky notes
• 足りなかったので = because it was not enough
• のりも = glue also
• 使いました = used

So the structure is:

[Using only sticky notes] + [was not enough, so] + [glue also] + [used]

This kind of sentence pattern is very common in Japanese:

• X だけでは 足りなかったので、Y も 使いました。
• Because X alone wasn’t enough, I also used Y.

You can make many similar sentences with it.
