[Solved] Grepping multiple strings from one column

I have 3-column tab separated data that looks like the following:

Code:
act of+n-a-large+vn-tell-v 0.067427
act_com of+n+n-a-large-manufacturer-n 0.129922
act-act_com-com in+n-j+vn-pass-aux-restate-v 0.364499666667
com nmod+n-j+ns-invader-n 0.527521
act_com-com obj+n-a-j+vd-contribute-v 0.091413
act on+ns+v-retreat-v 0.751588
act coord+ns-j+n-j-trash-n 0.751588
com obj+n-the+vn-pass-however-recreate-v 0.408118
act-com verb+ns-j+n-a-pull-n 0.3406765

I want to specifically grep the first column.
The possible combinations of the first column are the following:

Code:
act
com
act_com
act-act_com
act_com-com
act-act_com-com
act-com

I want to remove all of those lines that have the value 'act-com' in the first column.

What is the most efficient grep to do this?
I have tried

Code:
grep -w 'act\|com\|act_com\|act-act_com-com\|act-act_com\|act_com-com' input

However, it also considers 'act-com' as a valid string.
What should I do?

The desired output is the following:

Code:
act of+n-a-large+vn-tell-v 0.067427
act_com of+n+n-a-large-manufacturer-n 0.129922
act-act_com-com in+n-j+vn-pass-aux-restate-v 0.364499666667
com nmod+n-j+ns-invader-n 0.527521
act_com-com obj+n-a-j+vd-contribute-v 0.091413
act on+ns+v-retreat-v 0.751588
act coord+ns-j+n-j-trash-n 0.751588
com obj+n-the+vn-pass-however-recreate-v 0.408118

XmStringTableProposeTablist(library call)								 XmStringTableProposeTablist(library call)

NAME
XmStringTableProposeTablist -- A convenience function that returns a tab list SYNOPSIS
#include <Xm/Xm.h> XmTabList XmStringTableProposeTablist( XmStringTable strings, Cardinal num_strings, Widget widget, float pad_value, XmOffsetModel offset_model); DESCRIPTION
XmStringTableProposeTablist takes an XmStringTable structure containing tabbed compound strings, information on padding between columns, and rendering information and returns a tab list that, if used to render the strings in the table, would cause the strings to line up in columns with no overlap and with the specified amount of padding between the widest item in each column and the start of the next column. Each tab in the tablist would have the same unit type as units, an offset model of offset_model, and an alignment type of XmALIGN- MENT_BEGINNING. strings Specifies an array of compound strings. num_strings Specifies the number of compound strings in strings. widget Specifies the widget used for deriving any necessary information for creating the rendition. In particular, the XmNunitType of widget will be used to specify the unit type to be used in determining the amount of padding separating columns and for the tabs in the proposed tab list. Also, widget's render table will be used in interpreting rendition tags within the strings. pad_value Specifies the value of the amount of padding to be used to separate columns. The units for this parameter are specified as the XmNunitType set for the widget parameter. Refer to the XmNunitType resource of the XmGadget, XmManager, or XmPrimitive reference page. offset_model Specifies the offset model to be used in creating the tabs. Can be XmABSOLUTE or XmRELATIVE. RETURN
Returns a new XmTabList. The function allocates space to hold the returned tab list. The application is responsible for managing the allocated space. The application can recover the allocated space by calling XmTabListFree. RELATED
