We suggest that that two apparently contradictory insights about sign
language can be made compatible within a formal semantic analysis: (i)
the claim that directional verbs incorporate agreement markers/pronouns
(e.g. Lillo-Martin and Meier 2011); (ii) the observation that
directional verbs have an iconic component (e.g. Liddell 2003). We
sketch formal rules that integrate iconic requirements with
standard semantic conditions (be they presuppositional or assertive).
