i know prefixes added to verbs of motion gives them patterned meanings.
do suffixes do change the meaning of verbs of motion as well?
ive never heard of them.
are the reflexive endings 'ся' and 'сь' what you mean?
Suffixes also change meaning, or, in this case (тащить --> затащить --> затаскивать) grammatical category, such as aspect (perfect/imperfect). -ся (сь) is a suffix for reflective verbs (mind, though, reflective meaning is only one of their functions). That's, actually, why suffixes are different from endings. In Russian grammar "endings" are only those building blocks that only change the word's form while still keep its lexical meaning (such as singular/plural, 1st person verb form - 3rd person verb form). By contrast, suffixes and prefixes are part of the stem: they are used to alter the meaning of the word (so in English a Russian teacher would call "-ment" in "government" a suffix, but "-ed" in past form "sustained" an ending).

Strictly speaking, you should only be aware of a limited amount of verbs of motion, such as идти/ходить, ехать/ездить, лететь/летать, плыть/плавать, ползти/ползать, нести/носить, вести/возить and a few others. There are many other verbs that mean some motion, but only these few have a distinction between "indefinite" (multidirectional) and "specific" (one-way trip) action. All other Russian verbs only have perfective/imperfective aspectual distinction.

May I ask why so many questions in so little time frame?
