John 4:19

λέγει αὐτῷ ἡ γυνή· κύριε, θεωρῶ ὅτι προφήτης εἶ σύ.

Rough Word-by-word:
She says to him the woman, "Lord, I perceive that [a] prophet you are you."

Smooth Translation:
The woman said to him, "Lord, I perceive that you yourself are a prophet."

λέγει verb present active indicative 3rd singular from λέγω (I say) "she says"

αὐτῷ pronoun dative singular masculine "to him"

ἡ definite article nominative singular feminine "the"

γυνή noun nominative singular feminine "woman"

κύριε noun vocative singular masculine "Lord"

θεωρῶ verb present active indicative 1st singular from θεωρέω (I see/I perceive/I observe) "I perceive" (I don't know why the lexical form includes the variable vowel but the form here does not. Could this have something to do with accent rules? I note the long vowel on the ultima and the circumflex accent.)

ὅτι conjunction "that"

προφήτης noun nominative singular masculine "[a] prophet"

εἶ verb present indicative 2nd singular from εἰμί (I am) "you are"

σύ pronoun nominative 2nd singular "you"
