I hope are now convinced that the writer of the guide to Westminster Abbey is not 'ignorant', and does not write 'wrong sentences' with 'grammatical mistakes' in them. As to 'misericord', the word 'seat' is a lazy translation that is not helpful at all. Misericords are shelves on the underside of folding seats, visible when the seat is in an upright position. When the monks were standing for long periods at prayer, they could rest their behinds on these shelves to give themselves a bit of support and comfort. Over the years misericords also became a decorative feature. Do as Peachey suggests and stop relying just on a Russian dictionary. It is obviously misleading you. A translator should have more tools at their disposal than a bilingual dictionary. Use decent English-English dictionaries, together with the wealth of information available on the internet. Here are some links: https://en.wikipedia.org/wiki/Misericord http://www.misericords.co.uk/whataremisericords.html

Why use a Russian dictionary? :) Check again with an English-only dictionary. Look at definition 2 in the link below. It was something to lean against. http://www.thefreedictionary.com/misericord You can also do an image search, or check Wikipedia: https://en.wikipedia.org/wiki/Misericord

It's talking about seats which the Monks sat on. Underneath the seat there are carvings which cannot be seen (because they are on the underside). These carvings are called misrecords. So that is the name of the decorations.

Thanks for teaching me something new by asking this question!!

But Russian dictionary says that such word mean seats for monks. I am confused....
