訒

訒 means hesitate in speech. This is the word my daughter picked. We plan to pick one character word a day and have her learn how to speak, write and get the meaning.
This character is composed of 言=speak and 刃=stab. If speech is stabbed, then will be difficult to speak.
In cantonese,  訒 is sounded 'jan6', the 6^th tone.
