In other fragments WÉR also means again/back:
WILST WÉR FRY WÉSA ÀND VNDER MINA RÉD ÀND HODA LÉVA. TJÀN UT THEN. WÉPNE SKILUN THI WRDA. ÀND IK SKIL WÁKA O.ER THI.
Do you want to be free again... (etc.)
THÉRVMBE NIL HI NÉNE MODER WÉR HÁ
Therefore he doesn't want to have a mother back/again
WÉR is a multifunctional word as it can also mean:
- "was"; the past tense singular of "to be" (german: war)
- the root of "to defend" (dutch: weer)
- where (dutch: waar)
- true (dutch: waar)
- in expression INA WÉR; busy (dutch: in de weer)
From the context, it's clear that in the fragment I posted, it means back/again twice.
