The 1st highest number of forms (2) was observed with the lemma “2000”: 2000, 2000s.
The 2nd highest number of forms (2) was observed with the lemma “3000”: 3,000, 3000.
The 3rd highest number of forms (2) was observed with the lemma “billion”: billion, bn.
NUM occurs with 4 features: NumForm (464; 100% instances), NumType (464; 100% instances), Abbr (4; 1% instances), Number (1; 0% instances)
NUM occurs with 7 feature-value pairs: Abbr=Yes, NumForm=Digit, NumForm=Roman, NumForm=Word, NumType=Card, NumType=Frac, Number=Plur
NUM occurs with 6 feature combinations.
