OET interlinear ECC 1:3

uW Translation Notes:

Note 1 topic: figures-of-speech / rquestion

מַה יִּתְר֖וֹן לָֽ⁠אָדָ֑ם בְּ⁠כָל עֲמָל֔⁠וֹ שֶֽׁ⁠יַּעֲמֹ֖ל תַּ֥חַת הַ⁠שָּֽׁמֶשׁ

what? gain [belongs]_to,humankind in=all toil_of,his which,he_toils below/instead_of the,sun

Qoheleth is not using the question form to emphasize that there is no profit for humanity in all its toil. Instead, this is a genuine question. If a speaker of your language would not use the question form for that purpose, you could translate this as a statement or as an exclamation. Alternate translation: [I wonder if there is any profit for humanity in exchange for all his toil that he toils under the sun.]

Note 2 topic: figures-of-speech / abstractnouns

יִּתְר֖וֹן

gain

If your language does not use an abstract noun for the idea of profit, you could express the same idea in another way. Alternate translation: [advantage]

Note 3 topic: writing-pronouns

בְּ⁠כָל־עֲמָל֔⁠וֹ שֶֽׁ⁠יַּעֲמֹ֖ל

in=all toil_of,his which,he_toils

Note 4 topic: writing-poetry

עֲמָל֔⁠וֹ שֶֽׁ⁠יַּעֲמֹ֖ל

toil_of,his which,he_toils

Qoheleth is using a construction in which a verb and its object come from the same root. You may be able to use the same construction in your language to express the meaning here. Alternatively, your language may have another way of saying this.

Note 5 topic: figures-of-speech / idiom

תַּ֥חַת הַ⁠שָּֽׁמֶשׁ

below/instead_of the,sun

Qoheleth is using under the sun as a common expression of the culture to mean “in this life” or “in this world.” If this phrase does not have that meaning for your readers, you could use a comparable expression from your language that does have that meaning, or you could state the meaning plainly. Alternate translation: [in the world]
