Morphology

The form / lemma ratio of SYM is 1.000000 (the average of all parts of speech is 1.243237).

The 1st highest number of forms (1) was observed with the lemma “#”: #.

The 2nd highest number of forms (1) was observed with the lemma “###”: ###.

The 3rd highest number of forms (1) was observed with the lemma “$”: $.

SYM occurs with 2 features: Number (97; 11% instances), ExtPos (1; 0% instances)

SYM occurs with 3 feature-value pairs: ExtPos=PROPN, Number=Plur, Number=Sing

SYM occurs with 4 feature combinations. The most frequent feature combination is _ (814 tokens). Examples: $, /, -, :), +, :(, :-), A, :D, x
