Well... if you really wanna learn a language, i recommend you get some material to learn! I can tell you 'everyday phrases', but will you be able to use them on your own? will you know what the words mean? :P i hope you understand.
anyway.
hola = hello (informal)
nos vemos = see you (informal)
adios = goodbye (formal)
buenos dias = good morning (formal)
buenas tardes = good evening (formal)
buenas noches = good night (formal. mostly used when you're saying goodbye to someone at night)
gracias = thanks (formal)
muchas gracias = many thanks (formal)
disculpe, [algo] = excuse me, [something]. (formal)
disculpe, no hablo español = excuse me, i don't speak spanish (formal)
hope this helps :)
