This chapter will show that participles and modal infinitives are often used in the same syntactic environments as adjectives. For instance, the examples in (1) show that these elements can be used in prenominal attributive position. The fact that this position is usually restricted to adjective phrases and that the prenominal participles and infinitives carry attributive inflection is a clear indication that these elements are adjectival in nature. However, we will see that they also exhibit verbal properties.

The discussion is organized as follows. After a general discussion in Section 31.1, the attributive, predicative and adverbial uses of the elements in (1) are discussed in more detail in Sections 31.2 to 31.4. Section 31.5 concludes with some remarks on the modification of adjectivally used participles, as well as deverbal adjectives in general.
