And there are many roots that start with the letter מ, where the important part of the root follows, as מדנים (quarrel) comes from דין (judgement), ממזר (bastard) comes from זר (foreign), ממארת (malignant) has the root ארה (curse). And moreover, מרוח אשך (stones crushed) is from רוח (spirit), מֵאֵן (disagree) is from אין (not), מורך (faintness) is from רכך (soften), etc.

And moreover with nouns where the ת is in the root, it is usually added, as תהום (deep) is from המה, תכן (establish) is from כן, etc.

And in many roots, the מ that is in the end is added: צלמון (image) and חרום(maimed), etc.

And in many roots, the נ that is in the middle is added: איש (man) becomes אנוש, בת (daughter) becomes בנה.

And we find names that have four letters such that the final letter is added, asגבעול (stalk) comes fromגבע (small hill), גנזך (archive) comes from גנז (to store), etc. In particular, ר is found added also at the beginning and in the middle of four letters – רטפש (tender), שרביט (sceptre), שרעיף, שקערורות (hollow streaks).
