Coding issues with isolation of verbal morphology

[Leonid Spektor]

Harry,

	You need to understand the meaning of code symbols used by +sm option first. To get a full listing look in the CLAN manual or type "freq +sm" in Commands window, press return key.

The codes you are interested in are part of speech denoted by "|" symbol and PAST that can be denoted by either "-" or "&" symbols. Those symbols come straight from the words on %mor tier. For example word "worked" has %mor form "v|work-PAST" and word "went" has %mor tier form "v|go&PAST". 

You want to find all child speaker's verbs that are also in past tense, so your command would be:

freq +sm|v*,-PAST +sm|v*,&PAST +t*CHI +u *.CHA
