We argue that some parenthetical-like clauses in ASL can take both intermediate and maximally wide scope outside of if-clauses and attitude verbs. Specifically, we investigate embedded coordinations, of the form ... SAY [IF Clause-1 Clause-2 PLUS Clause-3, ...], and argue that Clause-2 may in some cases be interpreted with wide and intermediate scope (above SAY, or between SAY and IF). The key to our paradigm is that we mark the scope of IF and SAY with non-manual markers (Brow Raise and/or Role Shift). By exempting Clause-2 of these non-manuals, we force it to scope out of the relevant operator, including when it might be expected to create a syntactic island. Wide scope replicates the behavior of parentheticals and appositives in other languages. Intermediate scope is particularly interesting because it mirrors with full clauses the behavior predicted by some theories for some English appositives (Schlenker 2010, to appear a). The ASL data might thus lend support to the existence of a mechanism of high attachment in situ (McCawley 1998). Alternatives in terms of island-escaping covert movement or in situ indexing face significant challenges.

我们认为 ASL 中的一些类似括号的从句可以在 if 子句和态度动词之外采用中间和最大范围。具体来说，我们研究了以下形式的嵌入式协调......说 [IF Clause-1 Clause-2 PLUS Clause-3, ...]，并认为在某些情况下，Clause-2 可能被解释为广泛和中间范围（高于 SAY，或介于 SAY 和 IF 之间）。我们范式的关键是我们用非手动标记（抬眉和/或角色转换）来标记 IF 和 SAY 的范围。通过免除这些非手册中的第 2 条，我们迫使它超出相关运算符的范围，包括何时可能会创建一个句法孤岛。广泛的范围复制了其他语言中括号和同位词的行为。中间范围特别有趣，因为它用完整的子句反映了某些理论对某些英语同位词的预测（Schlenker 2010，出现 a）。因此，ASL 数据可能支持原位高附着机制的存在（McCawley 1998）。岛屿逃逸隐蔽运动或原位索引方面的替代方案面临重大挑战。
