通

verb: to pass through, to communicate, to understand
通

2 of the 3 candidate readings from Wiktionary confirmed for this general sense — genuine Chaozhou colloquial form not yet confirmed by a speaker. The third candidate, tang3, is attested only for the separate Southern-Min-specific 'throughout/completely' complement sense (see the other 通 entry), so this was split into two entries rather than merged.
