Jakob Jakobsen, An Etymological Dictionary of the Norn Language in Shetland…
“ O.N. hann, pron., he. — hain [hain] is doubtless the same word, noted down in the foll. tabu-term, belonging to fishermen’s lang.: (der ’r) a hain ahead o’ hersell [‘herself’] , there is a boat ahead of ours. “hersell” replaces “himsell”, which must be the older of these two words, as O.N. bátr, a boat, is of the masculine gender. Prop.: he (a boat) before him (another boat) . The term originates most prob. from S.Sh., where shø [‘she’] is used for “he” far more widely than in N.Sh. Cf. the use of the words hannister and hannepaa of a person or thing that one does not wish to mention by name. ”
