The original word in the Greek or Hebrew is translated by more
than one word in the English. The English translation is
separated by one or more other words from the original.
e.g. Mat. 15:30
Strong's No. G0630 English
to send away send G0630 G0000 her G0846 away G0630
Here the verb "send away" is split by the word "her". The zero
means the verb only occurs once in this passage not twice.
Sometimes five or six words separate a word.
Some exceptions are in Jer. 51:3 where the zero in
"bendeth H1869 H0000 let the archer H1869 H8802 bend H1869 H8799"
connects "bendeth" with "bend" not "archer".
