Morphology

The form / lemma ratio of SYM is 1.000000 (the average of all parts of speech is 1.243456).

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 3 features: ExtPos (156; 17% instances), Number (97; 10% instances), Abbr (29; 3% instances)

SYM occurs with 5 feature-value pairs: Abbr=Yes, ExtPos=ADP, ExtPos=PROPN, Number=Plur, Number=Sing

SYM occurs with 6 feature combinations. The most frequent feature combination is _ (687 tokens). Examples: $, /, :), +, -, :(, :-), A, :D, (:
