Forsooth! Never have I tasted so sweet a donut!
Verily! Yet ought you not proceed with caution, lest it should stain your officer's frock?
@ SirGod,
Is there an approximate equivalent in Romanian of 'lest' that is commonly used in the language? If there is, it would explain, but not justify, why 'lest' appears in the tests so frequently.
I'd say that it says that it's a word that is used sometimes, but not often. Take a look at some of the word's neighbours:
13 921 intrigued (past participle of lexical verb (e.g. given, worked))
13 922 attempts (-s form of lexical verb (e.g. gives, works))
13 923 destroy (base form of lexical verb (e.g. give, work))
13 924 intended (general adjective)
13 927 disgusting (general adjective)
13 930 witness (infinitive)
13 931 negotiating (singular common noun)
13 932 vine (singular common noun)
(All numbers added by me. Explanations copied from UCREL CLAWS7 Tagset)
Of course, all of these words have other forms and "lest" has only one, so they would jump over many one-form words if lemmas were counted instead of distinct strings. But then also "lest" would have a much better position, because the list would be much shorter. I'd say 13 934 is quite a nice achievement for such a word.
PS: I'm feeling quite uncertain about the way I'm using the data. I'd better stop.
I don't think that they want you to recognize a lest when you hear it. Solving their questions proves them that you have a good knowledge and comprehension of English's grammar, even if their questions are about things rarely or never used in conversations.
As far as I know, it doesn't have an equivalent on its own, we simply translate it as a phrase. But I highly doubt that someone translating from Romanian into English will translate the phrase as lest.
