মানিনী ঝেপেছে মুখ নিশীথিনী কেশে

 
“অভিমানিনী ঝেপেছে মুখ নিশীথিনী কেশে” can be translated poetically as:

“The sulking maiden has veiled her face with the tresses of the midnight night.”

or more naturally:

“The hurt-hearted woman hides her face behind the dark locks of night.”

A closer literary rendering:

“The aggrieved beloved has covered her face with the midnight’s flowing hair.”

Here:

• অভিমানিনী = a woman filled with অভিমান — a tender mix of hurt, pride, wounded affection, and emotional withdrawal (English has no perfect single-word equivalent)

• ঝেপেছে মুখ = has covered/hidden/veiled her face

• নিশীথিনী কেশে = in the hair/tresses of the night (night personified as feminine)

“Sulking” captures part of অভিমান, but Bengali অভিমানিনী is much softer and more romantic — closer to a beloved who has withdrawn because her feelings were hurt.

“মানিনী ঝেপেছে মুখ নিশীথিনী কেশে” is a very poetic line. A natural English rendering would be:

“The proud maiden has veiled her face with the tresses of the night.”

or more lyrically:

“The dignified lady hides her face beneath the flowing hair of midnight.”

Word meanings:

• মানিনী = a proud/self-respecting/dignified woman (often a beloved woman in poetry)

• ঝেপেছে মুখ = has covered/veiled her face

• নিশীথিনী কেশে = with the hair/tresses of the night (personifying night as a woman)

The imagery suggests a woman hiding her face behind dark hair, comparing the hair to the deep darkness of midnight. Very classical Bengali romantic symbolism.

The phrase “মানী ছেয়ে গেছে নিশিথিনী নিভৃতে” appears poetic, but I think there may be a typo in “মানী” (possibly “মণি,” “মাটি,” “মায়া,” etc.). Translating the words as written:

“The night has been covered in silence and seclusion.”

More poetic rendering:

“In the quiet solitude, the night has been gently veiled.”

• নিশিথিনী = the night (personified as a woman/lady of the night; a poetic word)

• নিভৃতে = in solitude, quietly, privately

• ছেয়ে গেছে = has covered / has spread over / has been enveloped

If you meant “মায়া ছেয়ে গেছে নিশিথিনী নিভৃতে”, it would be closer to:

“A veil of enchantment has spread over the silent night.” (very Tagore-like imagery)
