Ανακατεύω τον καφέ μου με το κουτάλι, ενώ διαβάζω τις ειδήσεις στο κινητό.

Because τον καφέ μου is the direct object of the verb ανακατεύω (I stir). Direct objects take the accusative case:

• ο καφές = the coffee (nominative, used for the subject)
• τον καφέ = the coffee (accusative, used for the object)

μου means my. In Greek, possessive pronouns like μου/σου/του/της commonly come after the noun:

• τον καφέ μου = my coffee
  You can also place it before for emphasis (less common in everyday neutral style):
• τον δικό μου καφέ = my coffee (emphatic: “my own coffee”)

In the present tense, ανακατεύω normally expresses an ongoing or habitual action depending on context. Here, with ενώ διαβάζω..., it clearly sounds ongoing at the same time (stirring while reading). Greek present tense is generally imperfective (action in progress / repeated).

με primarily means with, but it often expresses the means/instrument as well:

• με το κουτάλι = with a spoon / using a spoon
  Greek doesn’t have a separate “instrumental case,” so με + accusative covers this idea.

Nouns in Greek have grammatical gender. You learn it with the article:

• ο καφές (masculine)
• το κουτάλι (neuter)
  The article changes with case too:
• ο καφές → τον καφέ
• το κουτάλι → το κουτάλι (neuter accusative looks the same as neuter nominative)

In this sentence, ενώ means while (two actions happening at the same time):

• Ανακατεύω... ενώ διαβάζω... = I stir… while I read…
  It can also sometimes mean whereas/while on the other hand in contrast contexts, but not here.

Yes, with small differences in style:

• ενώ = common, neutral
• καθώς = also “while/as,” slightly more formal/literary sometimes
• την ώρα που = literally “at the time that,” more explicit
  All can work here.

Greek often prefers the definite article when referring to something specific/expected in context:

• τις ειδήσεις = the news (e.g., today’s news / the news feed)
  You can say διαβάζω ειδήσεις, but it sounds more like “I read news (in general)” or “I read news stories,” less specific.

στο is the common contraction of σε + το:

• σε το κινητό → στο κινητό = on/at the phone
  Similarly:
• σε την → στην
• σε τον → στον

στο κινητό means on the phone (device as the place/medium). If you want to specify “my phone,” add μου:

• στο κινητό μου = on my phone
  Without μου, it’s still natural if the context already implies it.

It’s flexible. You can also say:

• Ενώ διαβάζω τις ειδήσεις στο κινητό, ανακατεύω τον καφέ μου με το κουτάλι.
  Same meaning; starting with the ενώ clause can feel slightly more “scene-setting.”

Key stress points:

• ανακατεύω
• καφέ
• κουτάλι
• ειδήσεις
• κινητό
  Also note ειδήσεις has the stress on -δή- and is plural: η είδηση (singular) → οι ειδήσεις (plural).
