Modal particle
Modal particles (Modalpartikel in German) are always uninflected words similar to grammatical particles in English which are also uninflected. However, English grammatical particles in fact include function words such as sentence connectors[?], sentence substitutes[?], conjunctions, interjections and even adverbs, which German particles do not do. They are entities standing out for their simpliciy in German, a language which is so much more inflected[?] than English.
Modal particles are much purer in that their only function is that of reflecting the mood or attitude of the speaker or narrator. They do not refer back to what has been said previously but only what the speaker's attitude is to what has been said earlier. They do not stand in for whole sentences, and they do not exclaim when the speaker is in pain, for example, as interjections in English do.
Modal particles need to be learned in daily usage as there is practically no literal translation for each in itself other than that it helps form the phrase which on the whole conveys the way the speaker intends to sound, either to tone down opinions on the one hand or emphasize something on the other, to be conciliatory here or to give sharpness of expression there.
The way modal particles are used and when they are used, is very complex indeed, and it might be said that they form a kind of criterion of the speaker's grasp of the German colloquial[?]. If he uses the modal particles correctly he may be said to be in command of conversational German.
There are thirty or so modal particles in German, and a list is included of the most commonly-used words in alphabetical order. Each example shows an explanation of the intention behind its use, a short German phrase demonstrating it if possible and the nearest English equivalent - never a precise one as that would be probably impossible. It must also be born in mind that the full citation of each word could not be incorporated in anything less than a full-scale essay, and an encyclopedia entry cannot really do justice to such a task.
