(1) Trip or TRp - to satisfy, to please, to satiate, to radiate or emanate pleasure.
Here "R" is cerebral vowel "R" of Sanskrit.
Tarpit - Satisfied
Tripatii or TRpatI- Name of a girl - Meaning one who is satisfying or satisfied. "I" comes from the feminine form and has "I" as double "i" vowel of Sanskrit. "t" can come from Present Active Participle or it comes also from Passive Active Participle.
Interestingly another related word:
Tri-Pati - Three Lords - As an adjective for a woman, it means on who satisfies 3 Husbands or 3 Lords, like Draupati of Pandavas in Mahabharat was also called Panch-pati. This has the active principle. Or the one who is satisfied, the Husband or Lord, which has the passive principle. Note that it has common-ness in the rules with the previous word,
Tarpan (in Hindi the meaning has become opposite - which is often seen by and oen of my blogs shows examples) but it would mean pleasing, which is an Active Participle. Tarpan, Tarpant, and Tarpat are weak, middle and strong grade forms of the Active Present Participles. TRp next grade is Tarp.
Trap -It means perplexing, bashfulness, unchaste, shame in Sanskrit.
(2) Isa or ISa - to desire, to wish, etc. Here "S" is Cerebral "s" and a dental "s" can become cerebral "S" if previous vowel sounds are anything but "a" or "aa" sounds. It also means God which is omni-present in all direction in space.
So English words:
Trap - Now think what does the English "Trap" means. Do you see a connection with Sanskrit "Trap"? When you are trapped you are perplexed. When you are unchaste, others trap you as pariah.
Iso-trop-y or Iso-trop-ic - Which means which is not dependent on a particular direction and is the same or homogenous in all directions. Now "y" in Sanskrit is a semi vowel and sometimes used as a suffix for Adjective/Adverb, and "ic" is Sanskrit Adjective suffix - like in English. "Isah" can become "Iso" (Visarga "h" or hard "h" followed by a soft consonant or vowel, but t is a hard constant and "R" is a vowel, and by its own might "Tra" can be considered a soft sound - which is what Hindi takes it to be as an alphabet by itself). So it becomes "Desired or God (Omni Direction/Omni Present) - Satisfying/Radiating/Pleasing". So you see a connection?
An-iso-trop-y or An-iso-trop-ic - Which is opposite of the previous word - which is that which or whose property is dependent on a direction. In Sanskrit "An" prefix is used as an opposite for a word that beginning with a vowel (same like the English particle rule).
Trip - Some people say with the meaning that it was pleasant or joyful, and some people say it as a jouney - which one hopes would be pleasing and joyful. No one desires an unsatisfying journey.
