01.08.26: Are you a "river bore"?

The Facebook algorithm monster (or whatever it’s called) must have spotted my search for Classical quiz questions. There are far more than I realised, and quite a few to do with derivatives.

My Scots compatriot was confused about the construction, and used two life-lines: she first consulted her “phone a friend” but was not convinced by him. However, the host was confident, and she completely trusted him. Consequently, she got the correct answer: confluence.

The Latin preposition cum [+ ablative] means ‘(together) with’ and most commonly occurs when something is being done together with somebody else although it can be used in other contexts:

Cum amīcō in viā ambulō. | I’m walking with a friend in the street.

However, many Latin prepositions also act as prefixes; they can be added to, for example, verbs to give a more precise indication of the action:

(verb) eō: I go + (preposition) ex: out (of) > exeō: I go out; ex is now acting as a prefix

The preposition cum can also act as a prefix, but undergoes spelling changes. I don’t include all the meanings of each verb, some of which can have multiple definitions, but the ones which clearly show how the prefix is used.

currō: run > concurrō: run with others; ‘flock’ together

undique ex agrīs concurrērunt (Nepos): From the fields they came together from every direction, i.e. they were in separate locations but all ended up at the same place.

habitō: live > cohabitō: live together; cohabit

loquor: speak > colloquor: speak together; converse

claudō: lock; close + con- > conclūdō: finish; conclude

faciō: make > conficiō: complete; if something is confected, it is produced by combining different materials

I am keeping this to a fairly narrow definition since the prefix may also be used with verbs where the basic idea is not always obvious, but it usually conveys, for example, separate physical positions or unfinished parts of a task that reach an “end point”. The sense of ‘together’ often underpins the verbs.

The ‘end point’ in the quiz is where the separate rivers ‘flow together’:

cōnfluō [3]: flow together; also of people: come together in a crowd

> cōnfluēns: [which is] flowing together

> cōnfluentia, -ae [1/f]: (noun) flowing together; conflux

[A pronunciation / spelling shift occurs from La: -entia > OFr: -ence]

> Old French: confluence

> Middle English: confluence, or confluens (Middle English spelling is a bit ‘hit and miss’)

> Modern English: confluence

The prefix is in a wide range of nouns and verbs that were borrowed mainly via French but have their origins in Latin, and the original spellings of the prefix are retained:

collaborate; collect; collision;

commiserate; committee; community

concurrent; confer; conspire

It is also used to create new words:

co-author; co-direct; co-host; co-ownership

Once again, we can see Germanic and Romance roots coexisting:

We can either watch two Germanic streams (OE: strēam) flowing (OE: flōwan) together (OE: tōgædere), or we can win quite a lot of cash by knowing what the confluence of rivers means!

PS: Stan, her "phone-a-friend", wasn't 50% right - he was 100% right!
