[Tutor] Need better understanding of **kwargs

[Eduardo Vieira]

Hello, I thought I understood **kwargs until I stumbled with this function:

def changeflexion(myword, mytag, **dicty):
    global er_verbs
    global ar_verbs
    global ir_verbs
#    global dicty
    for item in dicty:
        if myword in item and mytag in item[1]:
            if dicty[item].endswith('ar'):
                ending = item[0].replace(dicty[item][:-2], "")
                try:
                    return dicty[item][:-2] + ar_verbs[ending]
                except KeyError:
                    return item[0]
            elif dicty[item].endswith('er'):
                ending = item[0].replace(dicty[item][:-2], "")
                try:
                    return dicty[item][:-2] + er_verbs[ending]
                except KeyError:
                    return item[0]
            elif dicty[item].endswith('ir'):
                ending = item[0].replace(dicty[item][:-2], "")
                try:
                    return dicty[item][:-2] + ir_verbs[ending]
                except KeyError:
                    return item[0]
            else:
                return item[0]

but when I import the module and call:
a = conjugate.changeflexion('estaban', 'VLFin', conjugate.mydict)
I get this error:
TypeError: changeflexion() takes exactly 2 arguments (3 given)
Isn't the 3rd argument supposed to be a dictionary?

Thanks for all the help this list has provided me as a novice
