Thonder
Over there - especially something distant but still visible. 'Thonder's the church' = there's the church (some way off but pointable to). The adverb pair to the demonstrative 'thon': if thon is 'that one', thonder is 'over there'.
Etymology
From Scots and Ulster Scots 'thonder', built on 'thon' (= that, yon) plus the locative '-der' suffix. The standard English 'yonder' is the parallel construction from 'yon' + '-der'; thonder is what Scots and Ulster Scots produced from the merged demonstrative 'thon'.
In a sentence
"Thonder's the gate - you can see it from here."
Historical notes
Thonder pairs naturally with 'thon' in modern Ulster Scots speech. The pair provides Scots and Ulster Scots speakers with a finer-grained deictic system than standard English: this/here, that/there, thon/thonder. The third level (thon, thonder) marks something further or more pointed-at than 'that'. Standard English speakers can manage the same distinctions with longer phrases - 'that one over there', 'all the way over yonder' - but the Ulster Scots compound is more economical.
