Quando acordo cedo, começo logo a bocejar e a espreguiçar-me na cama.

In Portuguese, the subject pronoun is often omitted when it is clear from the verb ending.

• acordo already means I wake up
• so eu is not necessary

You can say Quando eu acordo cedo, but Quando acordo cedo sounds more natural and less repetitive in many contexts.

Portuguese often uses the present tense for habitual actions, just like English does in sentences such as When I wake up early, I start yawning...

So:

• acordo = I wake up
• começo = I start

These are not necessarily happening right now; they describe a usual pattern.

Here, cedo is an adverb meaning early.

So:

• acordo cedo = I wake up early

Do not confuse this with the verb form cedo from ceder (I give in / I yield). In this sentence, it is clearly the adverb early.

No. In Portuguese, logo usually means right away, immediately, or soon depending on context.

In this sentence:

• começo logo a bocejar = I start yawning right away

So logo adds the idea that the action begins very quickly after waking up.

The verb começar is commonly followed by a + infinitive in European Portuguese.

So:

• começar a bocejar = to start yawning
• começar a espreguiçar-me = to start stretching

This is a standard pattern:

• começar a falar = to start speaking
• começar a trabalhar = to start working

Because both infinitives are linked to começo, and repeating the preposition a is very natural and often clearer in Portuguese.

So:

• começo a bocejar e a espreguiçar-me

means:

• I start yawning and stretching

You may sometimes hear structures where the second a is omitted, but repeating it is very normal and idiomatic.

Bocejar means to yawn.

It is not reflexive in this sentence, so there is no pronoun attached to it.

Examples:

• Estou a bocejar. = I am yawning.
• Começo a bocejar. = I start yawning.

Espreguiçar-se means to stretch oneself, especially after waking up or when sleepy.

The -me is the reflexive pronoun meaning myself.

So:

• espreguiçar-me = to stretch myself

This verb is commonly used reflexively:

• eu espreguiço-me = I stretch
• tu espreguiças-te = you stretch
• ele espreguiça-se = he stretches

In English, we usually just say stretch, but Portuguese often uses the reflexive form.

This is a very important feature of European Portuguese.

In European Portuguese, pronouns are often attached to the end of the verb with a hyphen:

• espreguiçar-me

This is called enclisis.

After an infinitive, especially in structures like começar a..., this is very common and natural in Portugal:

• começo a espreguiçar-me

In Brazilian Portuguese, you are more likely to hear:

• começo a me espreguiçar

But for Portuguese from Portugal, espreguiçar-me is the expected form.

In European Portuguese, espreguiçar-me is the standard and most natural form here.

• começo a espreguiçar-me = standard European Portuguese

Using me espreguiçar sounds more Brazilian or less standard in a Portugal-focused context.

Because bocejar is normally not a reflexive verb.

You say:

• bocejar = to yawn

not:

• bocejar-me

So in the sentence, one verb is non-reflexive and the other is reflexive:

• a bocejar
• a espreguiçar-me

That is completely normal.

Na is a contraction of:

• em + a = na

So:

• na cama = in the bed / in bed / on the bed, depending on context

In this sentence, the most natural meaning is simply in bed.

Other examples:

• no quarto = in the room
• na cozinha = in the kitchen

The comma separates the introductory time clause from the main clause.

• Quando acordo cedo, = When I wake up early,
• começo logo... = I immediately start...

This is very similar to English punctuation in a sentence like:

• When I wake up early, I start yawning...

Yes, but the nuance or rhythm may change slightly.

The original:

• começo logo a bocejar

is very natural and means I start yawning right away.

You might also see or hear:

• logo começo a bocejar
• começo a bocejar logo

But the original version is very idiomatic and smooth in European Portuguese.

Not exactly, though they can be similar in meaning.

• Quando acordo cedo = When I wake up early
  This sounds like a general repeated situation.
• Ao acordar cedo = Upon waking up early / When waking up early
  This can sound a little more condensed or formal.

In everyday speech, Quando acordo cedo is very natural and straightforward.

The ç is pronounced like s.

So espreguiçar has a s sound in that part of the word, not a k sound.

The cedilla (ç) is used before a, o, and u to keep the soft s sound:

• ça, ço, çu = sa, so, su

Without the cedilla, c before a would normally sound hard, like k.

Yes, it strongly reflects European Portuguese usage, especially because of:

• a + infinitive after começar
• the attached reflexive pronoun in espreguiçar-me

A Brazilian Portuguese version would often look more like:

• Quando acordo cedo, começo logo a bocejar e a me espreguiçar na cama.

Both are understandable, but the original is clearly Portugal-oriented.
