ह्वल्अ चलने
Class 1P
to shake, move
N.B. usually this dhātu would always be ghaṭ-ādi since ह्वल्अ is directly listed as ghaṭ-ādi, but gaṇa-sūtra limits that by saying that it is only optionally ghaṭ-ādi when it desn't come after an upendra । but सिद्धान्त-कौमुदी confirms that it is always ghaṭ-ādi when it does come after an upendra ।
