Questions & Answers about Ben tuvali boyuyorum.

Why does tuvali have an -i at the end? Isn’t the noun just tuval?

In Turkish, a definite/specific direct object takes the accusative suffix -ı/-i/-u/-ü (according to vowel harmony).

• tuval (canvas) + -ı → tuvali (“the canvas”).
  If the object is indefinite or generic (“a canvas” or “canvases” in general), you omit that suffix: tuval boyuyorum (“I’m painting a canvas”).

What does the -yor part in boyuyorum mean?

-yor is the present‐continuous tense marker in Turkish, corresponding to English “-ing” (am/is/are doing). You attach -yor to the verb stem, then add the personal ending (-um for “I,” ‑sun for “you,” etc.).

Why is it boyuyorum and not boya-yorum or boyıyorum?

The verb root is boya- (“to paint”), which ends in -a. When you add -yor, Turkish drops that final stem vowel:
1) boya- → boyu- (drop a)
2) boyu- + -yor → boyuyor
3) boyuyor + -um (1st-person ending) → boyuyorum

Is it necessary to say ben in Ben tuvali boyuyorum? Can I drop it?

You can drop ben. Turkish is a pro-drop language, so the ending -um already tells you the subject is “I.”

• Ben tuvali boyuyorum (with “ben,” for emphasis or clarity)
• Tuvali boyuyorum (more natural in everyday speech)

What’s the typical word order here? Why does the object come before the verb?

Turkish follows Subject-Object-Verb (SOV) order. If you include the subject, it comes first, then the object, then the verb at the end:
Subject (Ben) + Object (tuvali) + Verb (boyuyorum)

How would I say “I am painting the canvases” (plural)?

1) Form the plural: tuval → tuvaller (“canvases”)
2) Add accusative for a definite plural object: tuvaller + -i → tuvalleri
3) Build the sentence:
“(Ben) tuvalleri boyuyorum” → I am painting the canvases.

How would I turn it into past tense, “I painted the canvas”?

Use the simple past suffix -dı/-di/-du/-dü (vowel harmony). With boya-:
1) boya- + -dı → boyadı
2) boyadı + -m (1st-person) → boyadım
Put the accusative on tuval:
“(Ben) tuvali boyadım” → I painted the canvas.
