newbie question

Hello all,

I am trying to learn a little old Norse and i have a question 
i understand that ON uses word endings to indicate whether a word is masc or fem but does that change is pronunciation ? ex  Ulfr    if it has r at end is the r silent ?

 

also if any other new folks would like to work together or just talk give me a shout

 

thanks for the help
