In this paper, the word sense disambiguation (WSD) of English modal verb "can" is realized by the approach of formal concept analysis. The structural partialordered attribute diagram (SPOAD) is generated for the WSD of "can", and the accuracy reaches 92.99%. The normal and reversed SPOADs for each sense of can are generated in order to find the role of the contextual features in the formation of the senses of "can (ability)", "can (possibility)" and "can (permission)". It is discovered through examining and comparing the SPOADs of the three senses of "can" that in general, the extents of the three senses of "can" tend to be taken on by semantic features, and the intents of the three senses of "can" are taken on by both semantic features and syntactic features. A maximum common feature and a redundant feature are also discovered. The discovered knowledge provides important evidence for the feature selection in natural language processing and for the semantic analysis of English modal verbs.
