This article is a pilot study on the feasibility of investigating the grammar, both in terms of words and sentences, of the Gospel according to John in a systematic manner. The reason is that in general the commentaries and even specialized articles have different foci, inter alia, focusing on the historical nature or the theological and literary aspects that the Gospel is so well-known for. In surveys of commentaries on the Gospel it becomes apparent that real grammatical studies are far and few between, and that there is a tendency among commentators to copy grammatical material from one another. More often than not, grammatical issues are simply ignored and the unsuspecting and trusting reader will not even realize that there is a dangerous dungeon of grammatical problems lurking beneath the surface of the text. Apart from that, the significance of grammatical decisions are often underestimated in studies of John’s Gospel.
