Questions & Answers about Járnið verður fast í munninum.
Why use verður instead of er in this sentence?
This is the core of expressing future states in Icelandic. While er (from vera) means the metal is currently fixed in the mouth, verður (from verða) indicates a future state or a change ('will be' or 'will become'). We use verða to predict how things will turn out.
Why is the adjective fast instead of the dictionary form fastur?
Adjectives must match the gender of the noun they describe. Here, it describes járnið (the iron/metal), which is a neuter noun. Therefore, the adjective takes the neuter form fast instead of the masculine dictionary form fastur.
Why does í munninum use the dative case here?
The preposition í (in) takes the dative case when it describes a stationary position or location. Because the metal is fixed in the mouth rather than moving into it, we use the dative form munninum instead of the accusative munninn.
Does járnið mean 'the iron' or 'the metal'?
While járn literally translates to 'iron', Icelandic often uses it to refer to specific metal objects or hardware. In this context, it is most likely referring to a horse's bit being placed in its mouth, or perhaps a dental tool.
