to attend, to be present at [verb] [woonde bij, bijgewoond]

"Bijwonen" is composed of "bij" and "wonen" but contrary to what you
might expect, it does not translate as "to live at".  You use the verb
"bijwonen" when you are present at some kind of meeting or event, but
do not really participate in the activity.

Examples:
– "Wilt u de opname bijwonen? Dat kan. Bel naar het volgende nummer: …" 
("Would you like to attend the recording? That is possible. Call the following number: …")

– "Kun jij morgen de vergadering bijwonen, of ben je verhinderd?" 
("Can you attend the meeting tomorrow, or are you unable to go?")

– "Ik heb de bespreking alleen bijgewoond, ik heb niet echt deelgenomen aan het gesprek." 
("I was only present at the meeting, I did not really participate in the conversation.")

Related words:
– Toehoren: to listen to (other people in a meeting, etc.) [verb] [hoorde toe, toegehoord].
– Deelnemen: to participate [verb] [nam deel, deelgenomen].

Example:
– "Heb jij wel eens deelgenomen aan de marathon van Rotterdam?"
("Have you ever participated in the Rotterdam marathon?")

– Publiek: audience [noun] [het publiek, no plural].
– Wonen: to live, to inhabit [verb] [woonde, gewoond].

milestone, landmark [noun] [de mijlpaal, de mijlpalen]

"Mijlpaal" is composed of
"mijl" and "paal", which respectively translate to "mile" and "pole". The English "milestone"
apparently transforms into a "milepole" in Dutch 🙂 Just like in English the word "mijlpaal" is used to refer to an important event in history or in one’s life, and it is of course also a very popular project management term, see the Examples.

Examples:
– "Vandaag de 500e DWOTD! Een ongelofelijke
mijlpaal, al zeggen we het zelf 😉 ."
("Today it’s DWOTD 500! An incredible milestone, even though we say so ourselves 😉 .")

– "Dit project heeft de volgende
mijlpalen en resultaten:" 
("This project has the following milestones and results:")

– "En, heb je je mijlpaal bereikt, of heeft het werk vertraging opgelopen?" 
("And, have you reached your milestone, or has the work been delayed?" Note the expression "vertraging oplopen": "to get behind", where "vertraging" means delay.)

Related words:
– Prestatie: achievement [noun] [de prestatie, de prestaties].
– Paal: post, stake, pole [noun] [de paal, de palen].
– Kilometer: kilometre [noun] [de kilometer, de kilometers].
– Hectometerpaal(tje): ‘hectometre marker/stone’ [noun] [de paal, de palen].
– Project: project [noun] [het project, de projecten].

Extra:

In the old days, "mijlpalen" or
milestones were used to indicate the distance of one mile relative to a city
gate or next milestone, to inform travellers about their position. The modern
Dutch equivalent is the so-called "hectometerpaal", which is
located along the main roads in the Netherlands ("provinciale wegen" and "rijkswegen"). You often hear the word "hectometerpaal" or its diminutive "hectometerpaaltje" on the Dutch traffic news
to warn you for speed radars along the motorway. When you are not sure about the
speed limit, just check out the speed limit sign on the "hectometerpaaltjes". If there is no speed limit sign, the motorway speed limit
is 120km/h (on a "snelweg").

"Ouwehoeren" is composed of "ouwe" (from "oud") and "hoer", which translate to "old" and "whore", hence the literal translation would be "to oldwhore"… The related noun "geouwehoer" can be more ore less translated with "old wives chattering", but somehow the old wives ended up has whores in the Dutch language…:-)
