1。thereof
以”there”为前缀加上介词构成的词，如thereafter， thereby， therein， thereinafter， thereinbefore， thereon， thereof， thereunder， thereupon， therewith等，在文中具体指什么，需要读者依照合同的上下文来判断，因而理解起来比较复杂，请看下例：
This Agreement is written in the English language。 In case of any discrepancy between the English version and any translation thereof， the English text shall govern。 句中”the English version and any translation thereof”从上下文判断意为 “the English version and any translation of the English version”，即thereof一词代替of the English version。与以here开头的词如hereof的理解方法类似。
2。therein
该词意为in that， in that particular
context， in that respect，“在那里”，“在那点上”，“在那方面”，表示上文已提及的“合同中的”“工程中的”。如：the contract or any part thereof意为the contract or any part of the contract，合同或合同的任何部分。
3。thereto
