- **Variables**: `x`, `y`, `z`, ... +**Variables**: `x`, `y`, `z`, ...
Each variable is an expression. For any expressions M and N and variable a, the following are also expressions:
- **Abstract**: (λa M) +**Abstract**: (λa M)
We'll tend to write (λa M) as just `( \a M )`.
- **Application**: `(M N)` +**Application**: `(M N)`
Some authors reserve the term "term" for just variables and abstracts. We won't participate in that convention; we'll probably just say "term" and "expression" indiscriminately for expressions of any of these three forms. -- 2.11.0
