Ο παππούς μου θέλει ρεβίθια το μεσημέρι και φακές το βράδυ.

In Greek, a possessive like μου normally does not replace the definite article. So Greek usually says:

ο παππούς μου = my grandfather
literally, something like the grandfather of mine

That is the normal Greek pattern:

• ο φίλος μου = my friend
• η μητέρα μου = my mother
• το σπίτι μου = my house

So the article ο is not extra here; it is expected.

μου means my or more literally of me.

In Modern Greek, these short possessive forms usually come after the noun:

• ο παππούς μου = my grandfather
• η αδερφή μου = my sister
• το βιβλίο μου = my book

So English puts the possessive before the noun, but Greek usually puts this short form after it.

Grammatically, μου is a weak genitive pronoun.

θέλει is the 3rd person singular present of θέλω = to want.

So:

• θέλω = I want
• θέλεις = you want
• θέλει = he/she/it wants

Because the subject is ο παππούς μου = my grandfather, Greek uses θέλει.

Greek often uses plural forms for foods like beans, lentils, chickpeas, peas, and similar items, because they are naturally thought of as many small pieces.

So:

• ρεβίθι = one chickpea
• ρεβίθια = chickpeas

And:

• φακή = one lentil
• φακές = lentils

In real-life use, these plural words can also refer to the food or dish in general, not just to individual pieces.

After a verb like θέλω, Greek often leaves out the article when talking about food in a general sense.

So:

• θέλει ρεβίθια = he wants chickpeas
• θέλει φακές = he wants lentils

This sounds like a general preference or choice of food.

If you added an article, it could sound more specific, depending on context:

• θέλει τα ρεβίθια could suggest he wants the chickpeas or he wants that chickpea dish

So the version without the article is very natural here.

These are time expressions.

• το μεσημέρι = at noon, at midday, at lunchtime
• το βράδυ = in the evening, at night, in the nighttime context

The exact English translation depends on context. In a sentence about meals, they often feel like:

• το μεσημέρι = for lunch / at lunchtime
• το βράδυ = for dinner / in the evening

So the Greek words are a little broader than a single fixed English translation.

Because Greek very often uses the article in common time expressions.

These are standard phrases:

• το πρωί = in the morning
• το μεσημέρι = at noon / at lunchtime
• το απόγευμα = in the afternoon
• το βράδυ = in the evening / at night

So το here is just part of the normal way Greek expresses time.

It can be repeated, but Greek often leaves out words that are easy to understand from the context.

The full version could be:

Ο παππούς μου θέλει ρεβίθια το μεσημέρι και θέλει φακές το βράδυ.

But Greek naturally shortens it to:

Ο παππούς μου θέλει ρεβίθια το μεσημέρι και φακές το βράδυ.

English does this too sometimes:

• He wants chickpeas at lunch and lentils at dinner.

So the second θέλει is simply understood.

A learner might notice several different functions here:

• ο παππούς is in the nominative because it is the subject.
• μου is a genitive weak pronoun meaning my / of me.
• ρεβίθια and φακές are the things wanted, so they are the objects of the verb.
• το μεσημέρι and το βράδυ are accusative time expressions.

One thing that can be confusing is that some Greek noun forms look the same in nominative and accusative, especially in the plural or with neuter nouns.

No. Greek word order is fairly flexible.

The sentence as written is a very natural neutral order:

• subject: Ο παππούς μου
• verb: θέλει
• object/time details: ρεβίθια το μεσημέρι και φακές το βράδυ

But Greek can move parts around for emphasis, for example:

• Το μεσημέρι ο παππούς μου θέλει ρεβίθια.
• Φακές θέλει ο παππούς μου το βράδυ.

The basic meaning stays the same, but the emphasis changes.

It can mean both, depending on context.

Very often in everyday Greek, φακές refers not only to the ingredient lentils, but also to the dish made from them, especially lentil soup or cooked lentils as a meal.

So in this sentence, it can naturally mean:

• he wants lentils
• he wants a lentil dish

That kind of flexibility is common with food words.

A simple pronunciation guide is:

o pa-POOS moo THE-lee re-VEE-thya to me-see-MEH-ree ke fa-KES to VRA-thee

The written accent marks show which syllable is stressed:

• παππούς
• θέλει
• ρεβίθια
• μεσημέρι
• φακές
• βράδυ

So the accents are important because they tell you where the stress goes.
