Hey! I just thought of something if it could be proved right. We have seen several words that the present/future tense changed to past tense by simply adding -ed, just as in 'help' to 'helped', or removing the -y at the end replacing it with -IED, just as in 'rely' to 'relied'.

Others, can still be gotten by simply changing the entire word, just like 'go' to 'went'.

My question is, if past tense of come is came, what should be the past tense of welcome?
