"Concatenated" how?

• simplyruntogether (using concat operator, .)?
• (loosely speaking) "concatenated" with spaces-or|other:punctuation between words
• something else?

And - - if the first - - what criteria do you wish to impose where a leading word might be a base word either with modifiers such as "ed" or "ate" or "ly" appended or where the base is followed by the beginning of a new word? eg:

fortuneatelysergicacid...

ie, is that fortune ate lysergic acid or fortuneately^*1 lysergic acid

^*1 An unfortunate spelling error but it will suffice for an OTTOMH example
