A typical EFL first lesson often includes self-introductions of the kind like:
My name is Taro. I am 12 years old.
These clauses use relational Processes, which “serve to characterize and to identify” (H & M, p.210). These two categories may also be termed attributive, such as Taro characterized as a member of that class of beings called ’12 years olds’, and identifying, such as the identity of the person named ‘Taro’. Note the important difference between the two is that identifying relational clauses may be reversed (My name is Taro/ Taro is my name) whereas attributive clauses may not (I am 12/ *12 am I).
Within these two categories of attributive and identifying, we may also provide more information about Taro through three different types:
1. Intensive: Taro is tall (attributive) / Taro is the tallest in the class; the tallest is Taro (identifying)
2. Possessive: Taro has a black bag (attributive) / The black bag is Taro’s; Taro’s is the black bag (identifying)
3. Circumstantial: Taro is at home (attributive) / Home is Tokyo; Tokyo is home (identifying)
Relational processes “prototypically construe change as unfolding ‘inertly’, without an input of energy” (H & M, p.211). They are construed as ‘static’ as opposed to material processes which are ‘dynamic’. Also, whereas material processes construe the world of ‘outer’ experience (Taro is watching TV) and mental processes construe ‘inner’ experience (Taro likes Conan), relational processes may construe both ‘outer’ (Taro is in the living room) and ‘inner’ (Taro is happy).
