härrör

Could you clarify the intended meaning or field for the term "härrör"? It is not a widely attested term in standard Swedish, and its meaning can vary by domain. For example, it could theoretically refer to something in plumbing/engineering (a branch pipe or junction), biology, linguistics, or another field. If you specify the domain and the spelling you intend, I can generate a concise, neutral wiki-style article under 300 words.
