Þrengslum

Þrengslum is an Icelandic word that translates to "bottlenecks," "chokepoints," or "narrow passes" in English. It refers to a place where a passage or route is constricted, making movement difficult or restricted. This term can be used in a literal, geographical sense to describe physical terrain, or metaphorically to describe situations where progress is impeded.

Geographically, þrengslum can denote a narrow valley, a strait between two bodies of water, a mountain pass, or any other natural feature that narrows the available space for travel or passage. Such locations have historically been strategically important as they could be easily defended or could control the flow of traffic.

Metaphorically, þrengslum can describe any situation where there is a significant constraint or obstacle to progress. This might include economic bottlenecks, such as a shortage of a particular resource or a problem in a supply chain. It can also refer to bureaucratic hurdles, societal restrictions, or any other factor that creates a point of congestion or difficulty. The concept highlights a point of friction that limits overall capacity or flow.
