| Suffix | m\. u\. _ 0 _ | Outfix |
|
u\.y has #y items resulting from applying u
to suffixes of y , beginning with one of
length #y (that is, y itself), and continuing
through a suffix of length 1 . m\.y applies successive verbs from the gerund m to the suffixes of y , extending m cyclically as required. |
If x>:0 in x u\. y , then u
applies to outfixes of y obtained by suppressing successive
infixes of length x . If x<0 ,
the outfixes result from suppressing non-overlapping infixes,
the last of which may be a shard. x m\.y applies successive verbs from the gerund m to the outfixes of y, extending m cyclically as required. |
