Dear David,<br>
<br>
German has a use of <i>komm</i> (imperative of kommen 'come') which
may not be quite what you are looking for, but certainly similar:<br>
<br>
If, in a conversation, A says something that seems unacceptable --
typically, overstated -- to B, B will start by "Komm komm!" and then
mostly, though not necessarily, add a sentence that somehow
invalidates or restricts A's contention. For instance:<br>
<blockquote>A: Linda has never contributed anything to our club.<br>
B: Komm komm, she has at least organized last year's dinner party.<br>
</blockquote>
If I were to explain from Sprachgefühl why the verb 'come' is used
in this sense, I would think that 'come' here means 'rejoin the
communication and evaluation basis occupied by the speaker'. Maybe
other speakers could refine this analysis.<br>
<br>
And perhaps a speaker of European Spanish could use the occasion to
explain what <i>venga</i> 'come!' means if it introduces a
sentence.<br>
<br>
Best, Christian<br>
