Lexis meaning ‘word, phrase’ (hence lexicos ‘having to do with words’) and logos

- dead (are no longer felt in Modern English as component parts of words; they have so fused with the base of the word as to lose their independence completely. It is only by special etymological analysis that they may be singled out, e.g. -d in dead, seed, -le, -1, -el in bundle, sail, hovel; -ock in hillock; -lock in wedlock; -t in flight, gift, height).
high-productive (er, -ish, -less, re)
semi=productive (eer, ette, ward)
non-productive (ard, -cy, -ive) drunkard
6) Origin
- native (ness, -ish, -dom and the prefixes be-, mis-, un-)
- foreign (ation, -ment, -able and prefixes like dis-, ex-, re- are of foreign origin).
The adoption of countless foreign words exercised a great influence upon the system of English word-formation, one of the result being the appearance of many hybrid words in the English vocabulary. The term hybrid words is of diachronic relevance only. Here distinction should be made between two basic groups:

1. 
   Cases when a foreign stem is combined with a native affix, as in colourless, uncertain. After complete adoption the foreign stem is subject to the same treatment as native stems and new words are derived from it at a very early stage. For instance, such suffixes as -ful, -less, -ness were used with French words as early as 1300;
   
2. 
   Cases when native stems are combined with foreign affixes, such as drinkable, joyous, shepherdess. Here the assimilation of a structural pattern is involved, therefore some time must pass before a foreign affix comes to be recognised by speakers as a derivational morpheme that can be tacked on to native words.
   

Many commonly used derivational affixes are polysemantic in Modern English.
Ex. The noun-suffix -er is used to coin words denoting 1) persons following some special trade or profession, e.g. baker, driver, hunter, etc.; 2) persons doing a certain action at the moment in question, e.g. packer, chooser, giver, etc.; 3) a device, tool, implement, e.g. blotter, atomiser, boiler, eraser, transmitter, trailer
Many homonymic derivational affixes can be found among those forming both different parts of speech and different semantic groupings within the same part of speech.
Ex. the adverb-suffix -ly added to adjectival bases is homonymous to the adjective-suffix -ly affixed to noun-bases, cf. quickly, slowly and lovely, friendly.

There is also a considerable number of synonymous suffixes in the English language.
