One expression you might have heard or read is law samaHt, literally ‘if you will allow’, or less literally ‘excuse me’ or ‘please’.
The root of the second word is, of course, s – m – H, which conveys the idea of allowing.
Now look at the following pattern:
ma + letters one and two of the root + uu + letter three of the root
This will give you the following word: masmuuH, in English ‘allowed’.
This pattern forms the meaning of the ‘object of the idea’.
Here is the pattern again:
ma + letters one and two of the root + uu + letter three of the root
ma s m uu H
