Hi, I have a cell array (P) of size 5000x1. Each element of this cell array is another cell array of variable size which contains some words. The task is to find the words that are present in more than a certain number of elements (rows) of the array P. Thanks

What have you tried? If nothing, then why not? If you want help, show what you have done. Otherwise this becomes merely a doit4me.

Hint: You are not told which orientation the individual cell arrays are. You need to make them all the same orientation before you can get much further.
bar = cellfun(@(C) C(:), foo, 'uniform', 0);
Then you can pull all of the contents into a single array:
vertcat(bar{:})

Notice I wrote vertcat(bar{:}) -- pay attention to brackets.
