Read, mark, learn and inwardly digest.

I wondered why this quotation had found its way into a post about speaking, but in its entirety, it really does belong here.

Blessed Lord, who hast caused all holy Scriptures to be written for our learning:
Grant that we may in such wise hear them, read, mark, learn and inwardly digest them,
that by patience, and comfort of thy holy Word,
we may embrace,
and ever hold fast the blessed hope of everlasting life,
which thou hast given us in our Saviour Jesus Christ.   Amen

(Collect for the Second Sunday in Advent, Book of Common Prayer)

Mark my words!
The word mark is used in the same sense as in the prayer above – take notice of.

Believe you me!
This is an instruction to you to recognise the truth of what I am about to say.

Would you believe it?
A rhetorical question expressing surprise and often disappointment.

As a matter of fact…
…I am going to tell you something which is true.

To make a point
in speech means to stress the importance of something.  If you make a point of doing something, it is deliberate and meaningful to you.

It’s a moot point.
A moot used to be an assembly, where things were discussedA moot point has not been decided.

To stretch a point
means to agree to something beyond the limit normally allowed. (Concise Oxford Dictionary)  This could be allowing children to stay up late for a special occasion, for instance.

Not to put to fine a point on it…
…means the same as to put it bluntly.

Do I need to spell it out in words of one syllable?
The only word in this question with more than one syllable is “syllable”, which has three!

There’s a thin/fine line between…
…only a small difference (perhaps between acceptable and unacceptable behaviour).

Spare a thought for…
…might really mean, say a prayer for or see if you can help.

Talking nineteen to the dozen
doesn’t add up, but makes a lot of chatter.

In the light of…
…something has been explained, which affected the speaker’s views.  Things are clearer in the light.

When Jesus spoke again to the people, he said, “I am the light of the world.  Whoever follows me will never walk in darkness, but will have the light of life.”

St John’s Gospel Chapter 8 verse 12 (NIV)
