et

it is useful to know that 'et' is latin for "and."
this helps explain:

• et al. - short for"et alii" meaning "and others"
• etc. - abbreviation of "et cetera" meaning "and the rest"
• et tu, brute? - julius caesar's famous last words meaning "and you, brutus?"

'et', spelled out, is also the origin of the ampersand symbol - stay tuned ;-)
