Questions & Answers about Escribo cada noche tres cosas por las que siento gratitud.

Why is there no yo before escribo? Don’t you need the subject pronoun?

In Spanish you usually omit subject pronouns (yo, tú, él, etc.) when the verb ending already makes the subject clear.

• Escribo can only mean “I write” in the present tense.
• Because the -o ending already tells us the subject is yo, native speakers normally don’t say yo escribo unless they want to emphasize I (as opposed to someone else).

So:

• Escribo cada noche… = normal, neutral
• Yo escribo cada noche… = “I write every night…” (maybe in contrast to “you don’t”)

What’s the difference between cada noche and todas las noches?

Both usually translate as “every night”, but there’s a small nuance:

• cada noche – a bit more individualizing: it highlights each night as a separate occasion.
• todas las noches – more collective: emphasizes all nights as a group, regularly.

In practice, both are very common in Latin America and are almost always interchangeable in this kind of sentence:

• Escribo cada noche tres cosas…
• Escribo todas las noches tres cosas…

Both sound natural.

Why is there no article (la) in cada noche? Why not cada la noche?
