There are more words but they are from Tolkien's earlier conceptional periods. Tolkien likely changed these words as he evolved the aesthetics and completeness of the languages. You may even find languages that Tolkien later rejected. Do not mix words from different time periods unless you are familiar with the phonetic developments.

Gnomish

obra-

verb. to follow; to succeed

obra

adjective. close behind (of place), following, succeeding, next behind or after (time or place)

The adjective G. obra appeared in the Gnomish Lexicon of the 1910s with the glosses “close behind (of place), following, succeeding, next behind or after (time or place)” based on G. ob “after, close behind (time and place)” along with an adverbial equivalent G. obron (GL/61).

Neo-Sindarin: For purposes of Neo-Sindarin I would update this word to ᴺS. abor “following, succeeding, close behind (of place), next behind or after (time or place)” based on later S. ab “after”.
