prārthanā

 The word "prārthanā" translates to "प्रार्थना" in 

Sanskrit, meaning 'prayer' or 'entreaty'.

Detailed Explanation:

• Word Structure: The term prārthanā (प्रार्थना) is derived from the 
• Sanskrit root arth (अर्थ), meaning "purpose, desire" combined 
• with the prefix pra-, implying "forward" or "towards," forming 
• an action-oriented noun. Thus, it literally implies "an act of 
• seeking or requesting."
• Meaning: In Sanskrit, प्रार्थना commonly refers to a prayer, 
• supplication, or request made to a deity, guru, or revered person.
• It is frequently used in religious texts, rituals, and devotional 
• contexts to denote a heartfelt appeal or wish.

• Usage in Sentences:
  • सुप्रभातं, समस्तेषां प्रार्थना फलं स्यात्।
    (Suprabhātam, samasteṣāṁ prārthanā phalaṁ syāt.)
    "Good morning, may everyone's prayers be fulfilled."
  • जनेश्वरस्य प्रार्थना सर्वदा समृद्धिं ददाति।
    (Janeśvarasya prārthanā sarvadā samṛddhiṁ dadāti.)
    "The devotion/prayer to the Lord always grants prosperity."
• Synonyms in Sanskrit: Some synonyms include याचना (yācanā) 
• meaning "request or entreaty," and विनीती (vinītī) meaning "humble 
• appeal," but प्रार्थना remains the most standard and widely 
• accepted term for "prayer."

Therefore, if you want to write or use "prārthanā" in authentic Sanskrit, 

प्रार्थना is the correct representation.
