Emphasizing parts of sentence with 大抵 (たいてい, usually)


Consider this sentence:

> 私は[大抵]{たいてい}朝{あさ}にコーヒーを飲{の}みます。

Usually, I drink coffee in the morning.

I am trying to understand how to use emphasis with this construct. In English,
this statement seems open-ended, if not ambiguous.

I am trying to understand which of the following implied meanings is closest
to the original sentence; otherwise how would I modify the original sentence
to add the emphasis:

  * Usually, **morning is the only time** when I drink coffee.

  * Usually, I **don't drink anything other than** coffee in the morning. 

  * I drink coffee in the morning usually, **but not everyday**.

EDIT:

Thanks for the interesting answers so far. My synopsis of what has been
presented:

I surmise that 大抵朝に, owing to the に, describes an action as happening “in the
usual morning”. This form sounds open-ended.

(?) 大抵コーヒー: This construct doesn't make sense to me. 大抵 is an adverb, so it
wouldn’t be correct to use it to qualify a noun/object.

Use of しか:

Based on some cursory searching, しか describes an amount of something, so it is
not analogous to "only" as used in this context; だけ should be used instead.
But, running with that meaning nevertheless:

The first one confuses me, since しか is a noun, not a particle like だけ.
「私は大抵朝しかコーヒーを飲みません。」Does this mean "I, in the usual morning, only drink
coffee.", or, "I, only in the morning usually, drink coffee."

「私は大抵朝はコーヒーしか飲みません。」This form seems straightforward. "Considering my usual
morning, it is coffee only that I drink."

だけ seems to be the correct way of saying "only" in this context. Without 大抵, I
can say「私は朝だけコーヒーを飲みます。」, "Morning is the only time I drink coffee."

As far as alternate adverbs, I understand that I can use ほとんど毎日 to state that
the action happens "almost everyday".

I can also use 日課 to say "coffee is a daily routine." But I don't understand
the grammar since its lacks the action. What sense does it make to say "coffee
is a [daily] routine."?

The use of different particles to tag 朝: I understand that に describes an
action as happening in the morning. I understand that using は invokes
contrastive emphasis. What I am saying about drinking coffee only applies in
the morning, but not to any other time of day.

が can be used to invoke exhaustive subject form; i.e. coffee is the preferred
object. 「私は大抵朝にコーヒーが飲みます。」"In my usual morning, coffee is the only thing I
drink."




Though it depends on context, the following two are both possible as implied
meanings of the sentence [私は大抵朝にコーヒーを飲みます].

> Usually, **morning is the only time** when I drink coffee.
>
> I drink coffee in the morning usually, **but not everyday**.

Without any context, the latter is more likely.

The difference can be explained as one of grammatical interpretation. In the
former case, [大抵] modifies [朝に]. In the latter one [大抵] modifies [飲みます].

Not to be ambiguous, you can say:

> 私は大抵朝 **しか** コーヒーを飲みません。
>
> Usually, morning is the only time when I drink coffee.
>
> 私は **ほとんど毎日** 朝にコーヒーを飲みます。
>
> I drink coffee in the morning usually, **but not everyday**.

If you want to say:

> Usually, I **don't drink anything other than** coffee in the morning.

You can say:

> 私は大抵朝 **は** コーヒー **しか** 飲みません。
