Which word should be added to the prefix 'परि' (Pari) so that its combined meaning becomes "to leave / abandon" (छोड़ना)?

Let's combine the prefix 'परि' with the given root words to analyze their meanings:
* परि + हार = परिहार (Parihaar), which means to abandon, reject, avoid, or leave behind (छोड़ना/त्यागना).
* परि + ताप = परिताप (Paritaap), which means grief, remorse, or deep pain.
* परि + तोष = परितोष (Paritosh), which means satisfaction or reward.
* परि + जन = परिजन (Parijan), which means family members or relatives.

Therefore, adding 'हार' to 'परि' yields 'परिहार', matching the intended meaning of leaving or abandoning.
