Shit in French is spelled "merde", I am not sure why you put this here.
"Mardi" means "Tuesday" in French and that is very close to "mardo" plus "lundi" means "Monday" which is also very close to "lundo". Knowing that nouns end in -o in Esperanto. I didn't even have to guess what this meant.
I have never seen it spelled that way, regardless of pronunciation. http://dictionary.reverso.net/french-english/merde http://www.larousse.fr/dictionnaires/francais/merde/50601?q=merde#50489
It is not everyone in Québec that uses this. I did find it in an urban dictionary: http://www.urbandictionary.com/define.php?term=marde
Notice this is spelled in colloquial speech as though someone were talking and it is not usually written this way. In school, French Canadian students won't write "chu" for "je suis".
I think the adaptation of "merde" or "marde" is more used as a swear word. http://www.dictionnaire-quebecois.com/definitions-m.html
Or going even further back, to Latin:
- dimanche is from dies Dominica (the day of the Lord)
- lundi form dies Lūnae (the day of the moon)
- mardi from dies Martis (the day of Mars)
- mercredi from dies Mercuriī (the day of Mercury)
- jeudi from dies Iovis (the day of Jupiter)
- vendredi from dies Veneris (the day of Venus)
- sabato of course from the old Hebrew shabbat (Sabbath)
Watch out, now I'm starting to really nerd out about etymologies.
The English names of the week are actually also based on the Roman gods, but substituted with Germanic/Norse gods.
- Sunday is obviously the sun's day (after the Latin "dies Sōlis")
- Monday is the moon's day
- Tuesday is the Tiw's day (Tyr), god of war (just like Mars)
- Wednesday is Woden's day (Odin) (Woden actually doesn't have too much in common with Mercury. Maybe he's just too important to be left out)
- Tuesday is Thunor's day (Thor), god of thunder (just like Jupiter)
- Friday is Frige's day (Freya), goddess of love (just like Venus)
- Saturday is the only day still named after a Roman god: Saturn. After the Latin name for the day: dies Saturnī.
And another fun fact, the Japanese names of the days of the week are named after the planets that are named after the gods of the Roman system.
E.g. Tuesday is 火曜日 (literally "fire week day"), named after 火星 (literally "fire star"), which is the name for the planet Mars, just like the Latin name of the day. And each of the five planets is named after one of the Chinese elements: fire, water, wood, metal and earth. Then just add the sun and moon to complete the set of seven.
The Japanese originally took this system from the Chinese, but they use a numbered system nowadays. The cop-outs. :P
Very Interesting. Thanks for the great information! :)
I'm interested in etymology. So, I wanted to know more about in the topic. After some search, I found that Babylonians was the first to use the seven-day week.
In Arabic, the modern names (used since about the year 600) are numbered (from 1: Sunday to 5: Thursday), except Friday (الجمعة (Al-Jumu'ah); the day of gathering) and Saturday (السبت (As-sabt); the day of rest, and maybe relates to the Hebrew name).
I've found also that many other languages use numbered week-days!
