The term modem is defined by one dictionary (Am. Heritage) as modem is based on a compounding of modulator + demodulator, and I think it originated in English. Most languages seem to use the untranslated word modem for this concept, sometimes phonetically adapted to the language's normal pattern (e.g., French stresses modem on the final syllable like most other French words). The only non-international words I've found for modem so far are Icelandic mótald, based on mót "joining" or móta "to form" + the instrument suffix -ald Chinese 調制解調器 (pronounced tiáozhìjiětiáoqì in Mandarin) -- according to the dictionaries I looked at, this means something like "transfer-produce-solution-transfer-instrument", but fluent Chinese speakers are welcome to correct this translation if it's wrong Greek διαποδιαμορφωτής (pronounced [ðiapoðiamorfo'tis], I think), possibly from δι- "two" + απο- "from" + διαμορφω- "to form" + the (agent/instrument?) suffix -τής (again, corrections are welcome) Frisian oerset, related to oersette "translate" Do you know of any other unique translations of "modem"?
