"Interlingua Today" is a course for those with no previous knowledge of Interlingua. It has been designed for self-tuition as well as for use with a teacher.
The course contains sufficient vocabulary to handle many situations, and the grammar of Interlingua, being so simple, is almost exhausted.
The grammar is introduced in a particular sequence, so that points that are usually difficult for English speakers are left until later in the course.
The course contains an exhaustive section on grammar and a 2000 word vocabulary.
This key is an important part of the course, for it not only provides model answers, it also constitutes an excellent back-reference to the exercises in the course.
