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".
