The next episode of Lost is called Namaste.
नमस्ते namaste is a greeting, from Sanskrit namas "bow, obeisance" plus te, a dative second person singular enclitic (cognate with thee). So etymologically it means "obeisance to you." A more formal form is नमस्कार namaskār, from namas plus kāra "making, doing".
(As I understand it, namas is a neuter consonant-stem noun, with the nominative/accusative form namaḥ. Therefore the s in namaste is due to sandhi.)
namas is from the Proto-Indo-European root *nem- "to bend". (Not this *nem-.) According to Pokorny, *nem- is the source of various words meaning "grove" or "valley" (a valley being a "bent or curved place"), including Lithuanian Nemenas (the Neman river), Greek νέμος "wooded pasture", Latin nemus "grove", Old Irish nemed "holy place", and Welsh nant "valley".
The Latin word gives us nemoral, defined by the OED as "Of, relating to, or characteristic of groves or woods; living in or frequenting groves or woods".
All of them require nemoral snails. - 1657 R. TOMLINSON tr. J. de Renou Medicinal Dispensatory 524
